Swimming Pool Tips and Reviews

The sodium bromide debate in the pool industry often gets reduced to a scary word: bromate. But the real conversation is about exposure, how regulators model risk, and what happens when guidance is built on limited field data. Pool service professionals have used sodium bromide based algaecide products for decades, especially for stubborn yellow algae, and many were blindsided by the EPA-driven label language that says “not for use in outdoor pools.” That label shift sparked fear at distributors and on service trucks, even though the product remains legal to purchase. The bigger issue is how pool chemistry, real-world dosing, and actual human exposure differ from worst-case assumptions. A key scientific point raised is that bromate does not automatically equal harm at any detectable level, especially when exposure is tiny. The discussion leans on research suggesting the stomach’s hydrochloric acid can rapidly reduce a large share of trace bromate back into bromide, which is far less co...

The EPA interim decision on sodium bromide has sent a shock through the pool industry because it forces a label change that effectively removes outdoor pool use from products many pool service professionals relied on for fast algae knockdowns. If a sodium bromide-based algaecide now reads “not for use in outdoor pools,” distributors and retailers often stop stocking it entirely, even if the product chemistry did not suddenly change overnight. That’s why names like Yellow Treat and No More Problems keep coming up: they became shorthand for a simple, dependable algae treatment process that many technicians considered “bulletproof,” especially when paired with a strong liquid chlorine dose. A big piece of the controversy is bromate formation. Bromate is considered a probable human carcinogen, and the EPA’s interim approach assumes a worst-case scenario of 100% conversion from bromide to bromate in outdoor pools. Scott Hamilton explains that this is not chemically realistic, but it is cons...

Variable speed pool pumps promise energy savings, but most owners and even seasoned pool service pros still end up guessing at RPM settings. That guesswork shows up later as cloudy water, weak heater performance, noisy plumbing, or a filter that slowly clogs until circulation quietly drops. On the Pool Guy Podcast Show, Sean McDermott from H2 Flow Controls introduces the Nautilus VSF pump, built around a simple idea: speed is just a tool, but flow is the outcome that actually runs a pool. By monitoring real flow instead of relying on a theoretical pump curve, the pump targets consistent circulation that supports both water quality and efficiency.   The standout feature is adaptive flow, which lets you enter pool volume and choose a constant flow mode or a turnover mode. Instead of “set it to 2,200 RPM and hope,” the pump adjusts itself to maintain the required gallons per minute as conditions change. Filters load up gradually, in-floor cleaning systems cycle, water features op...

Residential pool care often gets treated like the “informal” side of the industry, even though most pool service pros spend their days in backyards, not at commercial facilities. That gap shows up in training: commercial operators can earn the CPO certification, but residential technicians frequently learn chemistry through trial, error, and scattered advice. In this podcast conversation, we dig into why that is a problem and why Bob Lowry’s approach to pool chemistry training became so influential. His material was built for the backyard professional, with clear explanations and poolside decisions you can actually apply on route, not just theory for the classroom. We also talk about how the Pool Chemistry Training Institute (PCTI) evolved after Bob Lowry and Greg Garrett passed away, and how HASA stepped in to keep the education alive. A key part of the story is access: the original training was a longer paid course, but the goal now is broad availability for residential pool service....

Summer is when pool maintenance stops being predictable and starts moving fast, especially for pool service professionals managing large weekly routes. As water temperature climbs, everything accelerates: sanitizer demand rises, algae prevention gets harder, and balance problems show up quickly between visits. Terry Arco from HASA frames it as a shift from “walking to running,” and it’s a useful mindset for seasonal planning. Weather swings, early heat, and surprise cool spells can scramble the old calendar that once centered on Memorial Day. The best defense is preparation and smarter timing so you are not reacting to problems after they explode on day five or day seven of a service cycle.   Warm water changes water balance in measurable ways, and understanding that helps you prevent surface damage and customer complaints. A key concept is the Langelier Saturation Index (LSI): temperature alone can move LSI, nudging water toward scale-forming conditions as it heats up. Calciu...

Pool filter cleaning is one of those pool service tasks that looks simple until you are standing there with a lid that will not reseat, a clamp that will not start, and a customer who wants the system running right now. This episode digs into real-world pool filter problems that rarely show up in manuals, especially on D.E. filters and quad cartridge filters. A big takeaway for pool technicians is that the “mystery” of a lid that will not close is often an O-ring issue, even when the O-ring looks fine. Brand-specific O-rings matter, and having the correct replacement on hand can turn a frustrating call into a smooth, professional repair while protecting your schedule and your reputation.   A practical fix we discuss is lubrication done the right way. Using silicone spray on filter O-rings can help them seat easier and may extend service life, while Magic Lube can provide extra slip when you need that final bit of compression. When the metal clamp and spring barrel nut fight yo...

Customer cancellations are one of the most expensive problems in a pool service business because they hit your monthly revenue, your route density, and your schedule all at once. When a pool service customer cancels, you do not just lose the check, you also create a gap that adds windshield time and makes your pool route less efficient. The episode digs into a surprising truth: many homeowners have a high tolerance for bad pool maintenance. They may ignore mustard algae, a broken pool cleaner, or even missed visits for weeks, especially if they are not using the backyard daily. That “grace period” is a warning and an opportunity, because a pool pro can often fix service issues and rebuild trust before the customer starts collecting bids from another pool company. A major cancellation trigger has nothing to do with your water chemistry or your weekly pool service quality: the customer sells the home. If you cannot connect with the buyer, the account can vanish even when you did everythi...

Cloudy pool water, visible algae, and that dull “off” look are almost never solved by dumping in more chlorine and walking away. A reliable pool water quality fix starts with understanding how circulation, filtration, and sanitizer demand work together. When a pool party spikes bather load, when a homeowner leaves the system in spa mode, or when a new service account has been neglected, the water can turn fast because contaminants rise while flow drops. The key mindset for pool service pros and DIY owners is simple: treat the pool as a system. Clear water depends on moving water through a working filter, then oxidizing and killing what’s in the water, then keeping that process going long enough to finish the job. The first lever to pull is filtration because poor water quality quickly clogs the filter and creates a vicious cycle. With a sand filter or DE filter, rising filter pressure (PSI) often signals restricted flow; you need to know the clean starting PSI so you can spot when the ...

Shopping for an automatic pool cleaner looks simple until you price out the long game. Suction side pool cleaners, pressure side pool cleaners, and robotic pool cleaners all remove dirt, but they behave very differently once you factor in ownership cost, downtime, and repairs. A suction cleaner is usually the most affordable upfront and often the easiest to keep running for years with basic replacement parts. A high-end cordless robotic pool cleaner can feel like the premium choice, but the real question is what it costs per season and what happens when it needs service. Thinking like a pool service pro means valuing reliability, repairability, and the day-to-day reality of how the pool gets used. The biggest blind spot with cordless robotic pool cleaners is service. After a few seasons, problems show up: water intrusion, drive issues, or battery decline. Because lithium-ion batteries must stay water sealed, most designs do not let you swap a battery like a power tool. The battery and ...

Pool water chemistry is where a profitable pool service route either stays smooth or turns into nonstop call backs. One of the biggest hidden mistakes is “eyeballing” test readings and relying on rules of thumb like always adding a quart of muriatic acid or half a gallon of liquid chlorine. That approach might have felt harmless when chemicals were cheap, but today it burns margins fast and can push water chemistry in the wrong direction. Using a dosing app or the dosage tables from a quality test kit turns guesswork into repeatable results. With basic inputs like pool volume, current pH, target pH, alkalinity, and acid strength, you can calculate an accurate dose in under a minute and avoid both waste and damage. Balanced water is more than clear water. True balance also means avoiding corrosive conditions that etch plaster, pit heaters, and trigger metal staining, while also avoiding scale forming water that crusts tile lines and clogs equipment. That is where the Langelier Saturatio...

 The Future of Pool Pump Technology: How Adaptive Flow Control Is Changing Pool Efficiency For decades, pool owners and service professionals have relied on variable speed pumps to improve energy efficiency and reduce operating costs. While these pumps represented a significant advancement over traditional single-speed models, they still required users to estimate the correct operating speed based on pool size, plumbing configuration, and equipment demands. A new generation of technology is aiming to eliminate that guesswork altogether. The Nautis™ Variable Speed + Flow (VSF) Pump from H2flow Controls introduces adaptive flow control, a technology designed to automatically adjust pump performance based on real-time flow measurements. By continuously monitoring water flow and adapting motor speed as conditions change, the system seeks to deliver optimal circulation while maximizing energy savings. Moving Beyond Fixed-Speed Programming Traditional variable speed pumps are often progr...

Pool service safety is not just a “be careful” reminder, it’s a set of repeatable habits that protect pool technicians, homeowners, and your business. On a pool route, risk shows up in obvious places and in surprising ones, especially when you are onboarding a new employee who did not choose the accounts. A smart safety culture starts with awareness, training, and the right protection, including thinking seriously about liability insurance. Even when you do everything right, accidents can happen in the field, and a single incident can turn into property damage, medical costs, missed work, and a lawsuit. The goal is to reduce exposure by spotting hazards early and building simple rules that are easy to follow every stop.   One of the most underestimated hazards for pool pros is backyard pets, including dogs that seem calm until the day they are not. A new dog can appear at a property with no warning, and a bite can be debilitating, disrupt a weekly service schedule, and trigger...

Training and onboarding a pool service employee is not a one-day task, because your route, your customer trust, and the long-term value of your pool business are on the line. A new pool technician will forget details, miss small steps, and run into situations they have never seen, even after weeks of ride-alongs. Planning for that reality is the first management skill: expect calls, expect small mistakes, and build a system that prevents problems from reaching the customer. For many pool service pros, three to four weeks of field training is a practical baseline, with clear standards for what “good service” looks like at every stop. Before you teach testing or brushing, you have to define culture, because culture sets the service level your employee will copy. Some companies run a numbers-first model where speed and volume win, while others protect premium customer service and spotless results. If you want consistency, say it out loud during onboarding and then back it up with training...

Phosphates are one of the biggest “hidden” drivers of recurring pool algae, even when the water looks balanced on paper. In pool water chemistry, phosphates are compounds made from phosphorus and oxygen, and they act as a primary nutrient for algae growth. That matters because algae doesn’t need much to take off: phosphate levels are measured in parts per billion, and small numbers can still keep blooms alive. Unlike chlorine, phosphates do not dissipate on their own. They do not evaporate with water, and they do not naturally break down in a way that reliably solves the problem. Over time, phosphates can build, and once algae appears you can get a nasty cycle where more algae activity leads to more measurable phosphate pressure and a faster slide into cloudy water and heavy chlorine demand. Understanding where phosphates come from helps you prevent the next outbreak. Fertilizer drifting in on the wind, landscape runoff, and organic debris like leaves can all contribute, but a major mo...

Pool service owners often think they’re “just cleaning pools,” but a pool service business is a real asset with measurable value. A stable pool route with documented service history, reliable billing, and consistent customer communication can be bought, sold, or used as an exit plan when you no longer want to be on the pole every day. The big shift is mindset: you are not only a technician, you are building a company with transferable systems. When you treat the business like something another operator could step into, you reduce risk, increase profit, and raise the valuation buyers are willing to pay. That’s why pool service management software matters so much during a sale. In acquisition due diligence, buyers are effectively purchasing your people, your customers, and your data. Clean, exportable records show that each account is real, long-term, and properly serviced, rather than a loose list that can’t be verified. Data security also becomes part of the deal, especially when a buy...

Pool service businesses don’t usually lose work because they lack skill in the field. They lose work because the phone rings while the tech is knee-deep in a backyard, driving to the next stop, or trying to finish routes before sunset. That gap creates missed calls, missed estimates, and missed new pool service customers who simply move on to the next company. On the Pool Grey Podcast Show, the conversation centers on practical AI for pool businesses: using artificial intelligence to reduce real labor, protect focus, and keep revenue from slipping away. The key idea is simple: if AI doesn’t save time and eliminate busywork, it’s probably just hype. That lens leads to a concrete example: Skimmer’s AI Phone, an AI receptionist built for pool industry workflows. Instead of a generic answering service, it’s designed to handle pool-related questions, qualify leads, and capture the details that normally require a human to stop what they’re doing. The system can create a customer record autom...

Pool professionals regularly face pools overwhelmed with dirt, mud, algae debris, construction dust, and storm-related contamination. While standard filtration systems handle routine maintenance well, heavy dirt loads often require more advanced cleanup methods. Over time, pool cleaning has evolved from basic hose vacuuming into specialized systems designed to handle extreme debris more efficiently, reduce filter strain, and speed up cleanup time. Traditional Hose and System Vacuuming The original and most common method uses a manual vacuum head, hose, and the pool’s filtration system. Debris is pulled through the skimmer or suction line and captured by the pool filter while clean water returns. This method works best for light dirt, routine maintenance, and small debris loads. It is simple, low cost, and widely used in residential service. However, it struggles with heavy contamination such as mud, fine silt, construction dust, and post-storm debris. Because everything passes through ...

Pool service work is full of problems you can solve with good testing, consistent chemistry, and steady brushing, but some jobs turn into “lost causes” when the customer’s expectations don’t match what the surface and water can realistically deliver. The key takeaway is not giving up on the customer, but being honest about limits, costs, and next steps. When you clearly explain what is cosmetic, what is structural, and what requires specialty gear, you protect your time, reduce conflict, and build trust. This mindset is especially important for pool stains, calcium scale, chronic water loss, and plaster discoloration because quick fixes often fail and the results can be unpredictable. Calcium buildup on pool tile is a perfect example. Light scale can respond to topical cleaners, a quality tile brush, or careful use of a pumice stone, but thick calcium carbonate becomes more like hardened rock than removable grime. Once buildup is heavy, especially around spillways and water features, s...

 Pool service success often comes down to small, repeatable habits that reduce mistakes on a busy pool route. One of the simplest upgrades is making sure each homeowner has a usable telescopic pole and a quality leaf rake. Too many backyards have a bent aluminum pole that will not lock, paired with a weak flat skimmer net that tears the first time someone tries to scoop debris from the floor. Recommending or supplying a sturdy pole and a real leaf rake helps the customer skim between visits, clean up before swim time, and handle surprises like a critter in the deep end. That single improvement can prevent emergency calls and save you an extra trip, which protects your schedule and your profit.   Timers are another quiet source of chaos in pool maintenance. In many markets, the Intermatic mechanical timer is everywhere, and knowing how it behaves can save you from chasing phantom equipment problems. Listen for the steady ticking and check the sight window to confirm the ge...

Pool service is a relationship business, but it’s also a safety business. When you’re dealing with resistant pool customers, the usual “the customer is always right” mindset can backfire fast. Pool maintenance and pool equipment repair decisions often involve pressure, electricity, chemicals, and real injury risk. The key is learning how to communicate like a professional: you respect the homeowner’s budget and choices, but you also explain consequences in plain language and document recommendations. This episode focuses on the practical reality of customer resistance, and how a pool service pro can stay calm, stay helpful, and still protect their route, reputation, and personal liability. One of the clearest examples is a cracked pool filter. To a homeowner, a small crack or pinhole leak can look cosmetic, like something you can ignore for another season. But a pressurized filter tank is not a cosmetic system. The crack can grow, the clamp and lid can fail, and the result can be explo...

Pool pump problems often look dramatic in the field, but the fix is usually simple if you know where to look. One of the most common headaches is a pump lid that feels welded on, especially on models like the Pentair WhisperFlo and some larger Jandy pumps. The lid is designed to stay tight under pressure, so forcing it with your palm can leave you with sore hands and wasted time. A rubber mallet is an underrated pool service tool: a few controlled taps on the lid corners while you hold tension can break the seal and let the lid spin free. For Hayward Super Pump and Super II style lids, a dedicated removal tool can be the difference between a two-minute stop and a full-on wrestling match, so keeping the right tool on the truck pays for itself quickly. When lids are abnormally tight or the pump starts showing air bubbles, cavitation, or priming issues, the pump lid O-ring is a prime suspect. The O-ring is the seal that makes the pump pot airtight, and even a small defect can let air in a...

Pool service work looks simple from the outside, but the real pros know the job is a long game: protecting your body, protecting the pool surface, and protecting your pool service business from avoidable mistakes. One of the fastest ways to shorten a pool technician career is skin exposure to harsh pool chemicals. Daily contact with chlorine, trichlor tablets, and muriatic acid can dry out hands, irritate skin, and create lingering discoloration. Even well meaning “protection” can backfire. Thin latex gloves can trap water and chemicals, effectively soaking your skin in chlorinated water for hours as you drive a pool route, creating more damage than going barehanded.   A better solution for pool technician safety is choosing gloves designed for wet work and chemical handling. Nitrile coated work gloves with a cloth backing stay comfortable, dry faster between stops, and help you keep a consistent routine: glove on for dosing and handling containers, glove off while driving, th...

Pool maintenance often fails for a frustrating reason: the homeowner unknowingly fights the system you are trying to keep stable. One of the biggest issues starts at the pool filter. When customers “take care of the filter” without understanding the details, filtration drops and the water never quite clears. With a DE filter, running with no diatomaceous earth, running with barely a dusting, or dumping in an entire bag can all cause cloudy water and poor performance. Cartridge filters get neglected too, with elements left in place for years until pleats spread, bands break, and the fabric clogs with oils and debris. For pool service pros, diagnosing these problems quickly is a key skill because a clean-looking equipment pad can hide a filter that is no longer doing its job. Filter neglect is not limited to DE and cartridge systems. Sand filters can be ruined by years of never backwashing, turning media into a hardened mass that channels and stops filtering, sometimes to the point where...

Pool filter PSI is one of the fastest ways to spot circulation problems, but only if you understand what the pressure gauge is actually telling you. PSI means pounds per square inch, and on a pool filter it reflects resistance as water tries to move through the system. As resistance rises, water flow back to the pool drops, which can show up as dull water, weak returns, a spa spillway that turns from a strong sheet into a trickle, or water features that barely run. The key pool maintenance habit is to learn your “clean filter pressure” for each pool, because every equipment pad, plumbing run, and filter type can start at a different baseline.   A clean starting PSI is your reference point, not a universal number. When a filter is freshly cleaned, note the gauge reading and treat it as the baseline for that specific pool. As the filter loads with debris, PSI often climbs and circulation slows, but the rate of change depends heavily on the filter design and surface area. In gene...

Shocking a pool gets talked about like it’s a single action, but it’s really a process of raising free chlorine high enough, long enough, to oxidize contaminants and kill algae. When a pool turns green, the root cause is almost always too little effective chlorine relative to what’s in the water. That “shock” word hides the real work: measuring conditions, adding enough liquid chlorine or cal hypo to reach a meaningful ppm target, then testing again because results are not instant. Think of it like cooking: you don’t check a cake after one minute and declare it done, and you can’t add a small dose of chlorine to a swamp and expect a miracle. For pool owners and pool service pros, learning the pool shock process means fewer return trips, faster green pool cleanup, and less frustration when chlorine seems to disappear overnight.   A practical starting point for a severely green pool or heavy mustard algae is an aggressive dose that matches the demand. A field proven rule of thum...

Pool service pros live for those “how did you do that?” moments, and nothing creates them like a fast green pool cleanup. When a customer has burned through hundreds of dollars in pool chemicals with no progress, your process is the difference. Two common approaches dominate: the floc method and the shock and awe method. Floc uses aluminum sulfate to bind suspended debris and algae, drop it to the floor, then you vacuum to waste after about 48 hours with the pump off. Shock and awe relies on raising free chlorine extremely high to oxidize algae and organics, then filtering out the dead material. Which option makes sense depends on your region, pool filter type, and whether you can vacuum to waste with a multiport valve. Speed comes from removing bottlenecks, and the pool filter is often the biggest one. In cartridge filter pools, old, compacted cartridges can slow circulation and trap fine debris poorly, making a green pool cleanup drag on. Swapping in new cartridges during a cleanup c...

Zero chlorine in a swimming pool is one of the fastest ways a clean backyard turns into a cloudy, algae-prone headache. For pool service technicians and homeowners, a “0 free chlorine” reading usually means more than just forgetting a dose. It often follows heavy bather load, a pump left off for days, not enough chlorine added last visit, or a buildup of organics that rapidly consumes sanitizer. The key pool maintenance lesson is speed: the longer the water sits without sanitizer, the more bacteria, microalgae, and debris multiply, and the harder it becomes to recover water clarity and safe sanitation.   A critical step is testing the right numbers, not guessing. When a pool zeroes out, combined chlorine (chloramines) is commonly present, which is why the water may smell “chlorine” while still being unsafe. Use a proper pool test kit that measures total chlorine and free chlorine so you can calculate combined chlorine (total minus free). This matters because breakpoint chlorin...
