Swimming Pool Tips and Reviews

DE filters earn praise for ultra-fine filtration, but they test the patience of even seasoned pool pros. This episode unpacks the real-world path from frustration to control, starting with the physics behind diatomaceous earth and why it catches debris down to about 3 microns. We set that against cartridge and sand performance to show where DE truly shines and where it drags a route down. Beyond theory, we examine the mess: caked powder in planters, residue on decks, and the constant risk of blowback when fresh DE finds a weak seal. The goal is not to scare anyone off DE, but to give you a clear, repeatable way to service these filters faster, cleaner, and with fewer callbacks. We map the market’s main DE designs so you know exactly what you are opening before the band clamp comes off. Quad-style DE uses thick cartridge-like elements, while the classic vertical grid assembly dominates most backyards, with brands like Pentair, Hayward, and Jandy following the same circular layout.

Dust is the silent profit killer in pool service. In desert and monsoon regions, a single wind event can fill a pool with fine silt that clogs pumps, drives up filter cleanings, and burns hours you can’t bill. The fastest way to get ahead is to decouple cleanup from the customer’s equipment. That means using tools that generate their own suction, filter independently, or discharge to waste without stressing the pad. This guide breaks down three solutions the pros rely on: the Advantage Portivac 2.0, the Bottom Feeder or Shrimp with a cartridge filter assembly, and the Vac Daddy with a vacuum-to-waste adapter. Each shines in different conditions, and choosing well can cut visit time, reduce callbacks, and protect margins across a dusty season. The Advantage Portivac 2.0 is essentially a portable equipment pad on wheels: a 1.5 HP pump paired with a 150 sq ft cartridge that lets you vacuum either to waste or back into the pool. The big wins are strong, consistent suction and a massive dir...

 Pool water looks simple on the surface, but what happens to your plaster, copper heat exchangers, and salt cells depends on one quiet referee: the Langelier Saturation Index. The LSI measures whether water will dissolve calcium from surfaces or deposit it as scale. Think of it as a balance beam where calcium hardness and temperature set the stage, and pH tips the beam one way or the other. When the index goes negative, water grows hungry and corrosive; go too positive and it snows calcium on tile, returns, and heaters. Many indexes exist, but LSI remains the pool industry’s common language because it translates real-world results—etched plaster, crunchy scale, rusted internals—into one actionable number. The bedrock of the LSI is calcium hardness. Set this wrong and every other move becomes guesswork. For plaster pools, 350 ppm is a reliable target; fiberglass and vinyl can ride leaner near 250 ppm, but everyone needs at least 150 ppm to keep water from pulling calcium from surfac...

Pool pH control sits at the heart of clear, comfortable, and protected water. pH is a scale from 0 to 14, with 7.0 neutral and 7.4 to 7.6 ideal for most pools. Drift too low and bathers feel itchy eyes and skin while metals and heater parts corrode. Drift too high and chlorine weakens, scale forms, and water clouds. The fix is not guesswork; it’s understanding buffers and cause-and-effect. Alkalinity, cyanuric acid, and borates all resist pH swings in different ways, and choosing the right chemical at the right time saves money, time, and surfaces. Total alkalinity is the primary pH buffer. High alkalinity blunts the impact of acid, making pH hard to lower; low alkalinity removes that cushion and lets pH plummet when you add acid. In plaster pools with chronic high pH, running TA around 70 to 80 helps acid work efficiently. In vinyl or fiberglass pools that drift low, keeping TA higher slows dangerous drops. This interplay explains why a single quart of muriatic acid can crash pH in a ...

Clear, stable pool water is not a mystery; it is chemistry applied with purpose. We walk through the seven parameters that truly control balance: pH, total alkalinity, calcium hardness, temperature, total dissolved solids, cyanuric acid, and the chlorine you measure to protect swimmers. Industry “ideal ranges” help, but they often leave a wide gap that causes confusion in day-to-day care. That is why we focus on target values inspired by Bob Lowry’s approach, then validate the interplay with the Langelier Saturation Index using tools like the Arenda app. When you aim at specific targets instead of broad ranges, you correct faster, stabilize sooner, and stop chasing your tail after every heatwave or rainstorm. Start with pH because it drives comfort, sanitization efficacy, and LSI. A steady 7.5 is practical and lands right where chlorine is effective without pushing the water toward corrosion or scale. Pair that with total alkalinity around 90 ppm to buffer pH without forcing it upward ...

Many pros want a single device that nails speed, accuracy, and price for pool water testing. The truth is less tidy: no one tester dominates every job. The Lamotte SpinTouch, photometers like PoolLab 2.0 and ColorQ, Taylor reagent kits, and test strips all have places where they shine and places where they fall short. The best results come from matching the tool to the task. When we stop hunting for perfection and build a flexible toolkit instead, our readings get more reliable, our routes run smoother, and our customers gain trust in what we present to them. Consider the SpinTouch as a specialized instrument rather than a daily driver. Its core appeal is speed and breadth: up to ten factors in about a minute, with optional discs for borates, phosphates, and salinity. Borrowed from medical diagnostics, the spinning disc and onboard optics deliver precise digital numbers with very little guesswork. The downside hits your wallet. The unit exceeds a thousand dollars and each disc is singl...

The Next Level of Clean — Now Even Bigger for Pool Pros For pool professionals, there’s a difference between simply picking up debris and delivering a pool that looks truly finished. The Bottom Feeder and Shrimp vacuum systems are already legendary for handling heavy debris like leaves, acorns, and large material with ease. But what about fine silt, dust, pollen, or dead algae? These particles often escape standard mesh bags, leaving a haze behind even after a thorough vacuum. We listened to that feedback — and built a better solution. Introducing the Cartridge Filter Assembly Extension Kit Double the Filtration for Very Dirty Pools For pools with heavy dirt loads, the Cartridge Filter Assembly Extension Kit is the upgrade you’ve been waiting for. Here’s what it includes: Cartridge connector insert Two extended support rods An additional 50 sq ft cartridge filter When installed, the Extension Kit allows you to stack two 50 sq ft cartridges , creating a total of 100 sq ft of filtration...

Liquid chlorine, also known as sodium hypochlorite, is one of the most dependable sanitizers for both service pros and homeowners because it delivers fast, predictable results without loading the water with stabilizer or calcium. The key is understanding its nature as an unstabilized chlorine and planning around sunlight and time. Commercial-grade liquid chlorine typically runs at 10 to 12.5 percent, far stronger than household bleach at 5 to 8.25 percent. This strength means a single gallon can raise free chlorine quickly for shock or routine boosts, with minimal side effects beyond a brief pH rise and a small sodium addition that has little practical impact on water balance. When you want a swift response—killing algae, breaking combined chlorine, or clearing a murky pool—few products match fresh liquid chlorine. The catch is that unstabilized chlorine does not linger. Sunlight strips it away unless the water has adequate cyanuric acid, generally between 30 and 80 ppm depending on cl...

Pool care runs on chemistry, yet many of the loudest rules come from habit, not science. This episode takes aim at three big beliefs: the acid “column” or “slug” method, the idea that liquid chlorine always raises pH, and the notion of “chlorine lock.” Each claim contains a grain of logic, which is why they persist, but the full picture clarifies what really happens in water. We also address swimmer safety after dosing—how soon you can get back in after adding chlorine or muriatic acid—and why circulation and cyanuric acid levels matter more than a blanket 24-hour rule. If you maintain pools for clients, this knowledge trims costs, protects surfaces, and keeps water safer and clearer. Let’s start with the acid column myth. The story says that pouring all your muriatic acid in one deep-end spot drops total alkalinity without much effect on pH, while walking it around drops pH more. It sounds plausible if you imagine acid “sinking,” but that mental picture fails at the molecular level. M...

 When a pool refuses to hold chlorine, the knee-jerk reaction is to add more. But most vanishing-chlorine stories start with movement, not chemistry. Poor filtration lets debris and organics linger, and weak circulation fails to spread sanitizer where it’s needed. Torn DE grids, an overused single cartridge, or starved pump runtime can turn a stable pool into a chlorine sink. Restore flow and run time first: clean or replace media, recharge DE, and aim for strong turnover with enough daily hours, especially in warm months. Once water is moving and clean, every other fix works faster and lasts longer. Water quality sets the chlorine demand. Cloudy or green pools carry a massive organic load that “uses up” sanitizer. That’s why a heavy shock in a swampy pool can vanish to near zero by morning even after adding gallons of liquid and bags of cal hypo. The water looks milky blue because the chlorine did its job killing algae and oxidizing waste, but the residual disappears under the loa...

Saltwater pools promise steady chlorine with less hassle, yet many owners wake up to zero readings and a confused control panel. The real problem rarely comes from a single fault; it’s a system of limits tied to water chemistry, temperature, flow, and equipment age. Start at the cell: scale on the plates acts like insulation that blocks current and slashes production. Even when your controller doesn’t flash a “clean cell” alert, thin calcium film can cripple output. A gentle acid bath using the ratio in your owner’s manual removes scale without stripping plate material. Over‑acid washing shortens cell life, so avoid strong mixes and long soaks. Make a habit of visual checks, especially with clear‑lid models, and plan light cleanings before peak season. Next, verify the salt level with a trusted tool rather than the panel alone. Controllers can drift or lie when a cell ages, showing false low or high readings that lock out generation. A handheld digital salinity meter pays for itself by...

Algae is not just a cosmetic problem for pool pros; it is a profit leak that drains time, trust, and chemical budgets. When a route hits peak season, even two algae-hit pools can add 20 to 30 minutes to a day, pushing back schedules and increasing frustration. That time compounds across a week, turning into real revenue loss, and it often cannot be billed if the cause is unclear to the homeowner. Worse, recurring algae erodes customer confidence. People pay for blue, swim-ready water, and when they see mustard streaks on steps or stubborn patches in corners, they question the service, not the many variables behind the scenes. Keeping that trust demands a plan that reduces blooms before they start. A key pillar is understanding why algae appears even when free chlorine tests “good.” The relationship between cyanuric acid and free chlorine sets the actual floor for sanitizer strength. Using Bob Lowry’s guideline, maintain free chlorine at a minimum of 7.5% of CYA. At 80 ppm CYA, that mea...

Calcium hypochlorite, known as cal hypo, is a staple sanitizer for many pool professionals because it delivers strong oxidation in a compact, shelf-stable form. Its percentage strength varies by source: pros often buy 73 to 78 percent, while big-box stores carry around 65 percent. Strength by weight matters when you compare products. A practical field rule equates roughly one pound of 73 percent cal hypo to one gallon of 12.5 percent liquid chlorine, even though the true math says about 22 ounces is closer. That near-parity makes cal hypo useful for routine shocking and midweek boosts, especially when you want portability and fewer heavy jugs. Still, it’s not just about free chlorine output; you need to think through side effects, regional water conditions, and safety. Safety sits at the center of using cal hypo well. Never mix it with trichlor or dichlor, which contain cyanuric acid; the reaction can be violently exothermic and explosive in feeders, skimmers, or buckets. Avoid putting...

Crowded pool days can turn clear water cloudy fast, but a few smart steps before guests arrive protect clarity, comfort, and budget. Bob Lowry lays out a simple plan: raise free chlorine a few ppm, add a measured dose of non-chlorine oxidizer, and keep the circulation system running throughout the event. The surprise hero is the shower. A quick rinse removes sunscreen, deodorant, lotions, and oils that devour sanitizer in the first minutes after swimmers enter. Studies show pre-swim rinsing can cut chemical demand dramatically, which means fewer chloramines, better smell, and happier eyes. Pair that with a steady filter and you trap organics early, letting chlorine focus on disinfection instead of cleanup. Many service techs run into a different headache: sky-high cyanuric acid from heavy trichlor use. For every 10 ppm of chlorine dosed via trichlor, about 6 ppm of cyanuric acid remains. Over weeks, that creeps upward, forcing the required free chlorine residual to rise to maintain the...

Pool chemistry rewards careful thinking and punishes assumptions. One of the stickiest myths is that cyanuric acid declines when water evaporates, so trichlor tablets can be used freely in hot, dry climates. Distillation physics says otherwise: evaporation removes pure water only, leaving behind calcium, salts, cyanuric acid, and everything else dissolved. When trichlor adds 10 ppm of free chlorine, it also contributes about 6 ppm of cyanuric acid. At a typical 10 ppm chlorine demand per week, CYA can rise roughly 25 ppm per month and 100 to 150 ppm over a season. That buildup weakens chlorine’s effectiveness and forces partial drains or backwashing to reset levels, because splash-out and leaks are the only real exits for CYA, not evaporation. Every chlorine choice carries a byproduct tradeoff. Trichlor and dichlor add cyanuric acid, liquid chlorine adds salt that becomes part of total dissolved solids, and calcium hypochlorite adds calcium hardness. The question isn’t whether byproduc...

Clear blue water hides a lot of chemistry. In this conversation with industry legend Bob Lowry, we trace two common pain points that can rattle even seasoned pool techs: sudden black stains after dosing with calcium hypochlorite and the real health stakes when a pool slips to zero chlorine. The black stain scare can feel like a catastrophe, but it’s usually copper revealing itself, not a new problem. Copper sulfate can sit quietly on plaster, masked by the blue of the water. The instant cal hypo lands on it, oxidation shifts the compound to copper oxide, which is black and obvious. What changed isn’t the metal load, only its form—and that insight reshapes how we fix it. Once you confirm a metal stain, you have options. Ascorbic acid can lift the stain from surfaces, but it doesn’t remove copper from the system. Without metal removal, the stain returns as soon as chlorine wipes out the reducer. That’s where sequestrants and chelants come in: they surround dissolved metal and keep it fro...

Water scarcity no longer sits on a far horizon for pool owners and service pros; it is here and shaping how we build, filter, and maintain pools. The old habits—hosing decks, routine backwashing, and full drains every few years—made sense when water felt endless. Today, drought cycles, stressed aquifers, and stricter municipal policies put pools under a spotlight. The good news is that pools can be part of the solution. With smart filtration choices, measured chemistry, and a mindset shift from water as commodity to water as asset, we can protect clarity, protect budgets, and protect a resource that keeps getting tighter. This episode traces the evolution from 1970s practices to present-day stewardship, and it offers a practical roadmap any operator can follow. History explains how we got here. During earlier droughts, restrictions focused on lawns and outdoor watering schedules, not pools. That changed after California’s severe 2012–2016 drought, when policymakers questioned new pool ...

 Bob Lowry’s name still carries weight on pool routes for a simple reason: his chemistry lessons work the very next day. This conversation with Terry Arco traces how those lessons are being condensed, modernized, and delivered to pool pros across the country in 2026. The core idea is practical education for residential service techs who face tight schedules and shifting water conditions. Rather than asking pros to sit through a six-hour seminar, Terry explains how the essentials of water balance, cyanuric acid management, and free chlorine control can be taught in focused sessions that respect the realities of field work while preserving scientific rigor. At the center of this push is an abridged course derived from Bob’s 252-page Pool Chemistry for Residential Pools and its concise 26-page companion, Pool Chemistry for Service Pros. The shorter format keeps the vital principles intact: understanding Langelier Saturation Index (LSI) to prevent scale and corrosion, managing CYA to p...

 The new season is the perfect time to audit your truck and upgrade the tools that decide your pace, quality, and profit. We start with the backbone of daily service: the pole. Carbon fiber poles have matured into a clear win for pool service pros because they’re lighter, stiffer, and more durable than aluminum, which means fewer sore backs and faster control when netting, brushing, and vacuuming. Among SkimLite, Ultimate Pool Tools, and Primate, the Primate pole stands out for its feel, balance, and vertical lever locks that adjust fast with one hand. The 3-piece Primate 3X collapses to six feet for small truck beds yet extends to cover most pools from one side, reducing time and fence-dings. If your route demands a 2-piece, the 8x15 2X works well, but the key is investing in a lighter, stronger pole that you grip 90% of the day. Vacuum systems have diversified, and choosing right can change your week. Cart units like Riptide and Hammerhead still rule heavy debris and large proper...

 Commercial pool service looks glamorous from a distance: bigger checks, steady contracts, and name recognition with HOAs and property managers. Up close, the margins collapse if you bid like a residential route and ignore compliance, access, and payment risk. The fastest way to protect profit is to price for the real workload and add a defined headache factor. That premium covers health department inspections, chemistry logs, weekend surges, and gate or access problems that spike usage. It also buffers late payments from management companies. Treat commercial work as a different product with stricter standards, not a scaled-up backyard job. Start with demand: HOAs, apartments, hotels, and community centers often must collect multiple bids. This is your opening if your online presence makes you discoverable for “commercial pool service” and local city names. Use SEO and targeted ads that call out HOAs, property managers, and compliance. Then, build direct pipelines. Call management...

Reliability in pool service begins long before you lift a leaf rake. The core shift is moving from ad‑hoc tasks to an ingrained routine that repeats at every stop. Consistency keeps clients confident and keeps you safe. Doing pools on the same day and around the same time each week helps homeowners anticipate your visit, but the deeper value is mental rhythm: clean in a set order, check baskets at a defined point, and dose chemicals last so you never wonder two stops later if you treated the water. A reliable routine also cuts risk. Skimmer lids left off cause sprained ankles; placing your vacuum hose through the deck into the skimmer creates a physical reminder underfoot so you don’t step into an open hole. Little habits like a final glance back for the chlorine floater protect both your body and your reputation. Timing your arrival to match running equipment turns minutes of guesswork into seconds of clarity. When the pump is already on, minor leaks show themselves, cleaners that sho...

Clear agreements turn messy pool jobs into manageable work. Too many service pros rely on verbal promises, then face blame when stains, cloudy water, or old equipment fail at the worst moment. The core fix is simple: put expectations in writing. A one-page service agreement and targeted waivers for special work like green pool cleanups and acid washes clarify scope, timing, risks, and client duties. They are not ironclad legal contracts, but they defuse disputes, set a steady tone, and keep your cash flow on track. When a client can read what you do, when you do it, and what you don’t cover, small issues rarely grow into cancellations or chargebacks. Start with a basic service agreement that outlines what you service each visit, billing cycles, late fees, and cancellation terms. Spell out what’s included versus billable extras like filter cleans, parts, or emergency visits. Add weather exemptions, vacation pauses, and chemical policies so rain, heat waves, or supply swings don’t become...

Budget-conscious clients are a reality in pool service, and they can come from any income level. Some are wealthy homeowners who got that way by pinching every penny; others are families simply trying to make ends meet; some view frugality as a cultural value. The common thread is the pressure they put on your time, tools, and patience. When an owner refuses to replace a dying pump or a rusted filter because it still technically runs, you feel that friction in longer service times, unreliable outcomes, and the constant sense that you’re failing their pool despite doing your best. The key is knowing when to accommodate and when to draw a line, because not every cost-saving request is harmful, but many become a slow drain on your business. Consider old equipment that limps along. You can explain performance loss, vacuuming limits, and filtration inefficiency, yet a client might counter that they only care the water looks blue. That mindset undermines your service standards and steals min...

Pricing shapes every decision a pool service business makes, and the 2026 State of the Pool Service Report by Skimmer puts hard numbers behind those choices. The headline: average weekly service sits around 225 dollars monthly in Sunbelt markets, with filter cleaning at 111 dollars and salt cell cleaning at 67 dollars. That average is not a universal rule, though. California and parts of Florida often run lower, while Texas pushes higher. The smart move is to treat the report as a compass, not a contract—an anchor for negotiating your rates, checking your competitiveness, and finding margin in places customers rarely scrutinize, like one-off maintenance tasks and specialty services. Billing models can make or break cash flow. The data shows 76 percent of pros use monthly billing, 19 percent bill per stop, and a small fraction do something else. Monthly billing wins because it smooths revenue, keeps quotes simple, and quietly captures those five-week months. Per stop billing is cleaner ...
