Swimming Pool Tips and Reviews

The pool service trade sits at a strange crossroads when the economy slows. We feel every shock in fuel and freight, yet we’re protected by the simple truth that clean, safe water takes time, skill, and consistent care. When oil rises, distributors pay more to move chemicals, equipment, and parts. That cost moves to your supplier, then straight to your invoice. You can’t absorb it and survive. The smart move is to align your pricing with reality before you bleed margin, while keeping client trust by being clear, steady, and measured in how you adjust. History helps. In 2008, housing collapsed and builders vanished under leverage. COVID was different: demand spiked and stimulus masked the pain, but shortages and panic buying drove inflation anyway. Today’s pressure sits in logistics. Fuel hits every pallet and delivery, so chemical prices rarely retreat once they climb. That stickiness is why waiting for prices to fall is a gamble. You can buy ahead for summer if cash flow allows, but d...

 If you’re a pool service pro trying to pick a cordless pool vacuum that truly fits your pool route, the choice between the Bottom Feeder and the Shrimp Cleaner comes down to how you actually clean day to day. Both are designed as independent, battery-powered vacuum systems that you can drop into a pool or spa without cords, plugs, or a separate pump setup, which is the real advantage: speed. The Bottom Feeder has built a reputation as the pro-grade benchmark because it’s built from aluminum with serious components and strong thrust, so light debris in a 15,000-gallon pool can be handled in just a few minutes. That kind of time savings matters when you’re moving stop to stop and trying to protect your schedule, your body, and your profit. Physical size and handling are the next decision points. The Bottom Feeder is compact for what it is, but the Shrimp Cleaner is noticeably smaller and lighter, which changes how it feels on steps, benches, spas, fountains, and tight corners. A sma...

Precision keeps pools clear, efficient, and safe, yet most confusion comes down to two tiny measurements: microns and parts per million. Microns tell us what size particles a filter or cleaner can catch, while PPM tells us how much chemical exists in a huge body of water. When you link both, cloudy water and over-chlorination myths fade fast. A micron is one millionth of a meter; human hair is about 70 microns, a grain of salt near 100. This scale matters because your filter’s rating determines what actually stays in the pool or gets removed. Sand filters typically capture 25 to 30 microns, cartridge 10 to 20, and DE 1 to 3, which is why DE yields the sharpest clarity. Since the human eye can only see down to roughly 35 microns, much of what irritates owners is invisible until the right filtration grabs it. That truth reframes expectations: if you run sand, you will not polish out fine silt the way a DE system does. Vacuum system bags and robotic canisters bring microns to the deck lev...

Many service businesses reach a fork in the road: take on employees and scale, or stay lean and protect margins and sanity. Pool service highlights this tension because the work is mobile, seasonal, and reputation-driven, and hiring has grown harder. Gig platforms like Uber, DoorDash, and Amazon Flex now lure exactly the people who once considered pool tech roles, offering flexible hours, quick onboarding, and decent pay with tips. Add rising minimum wages and you get a labor market where paying per pool or entry-level hourly rates struggles to compete. That pressure pushes many owners to remain solo even as demand grows, forcing them to pick between long days or saying no to new accounts. Beyond labor supply, a hidden barrier is the knowledge gap around scaling. A seasoned solo owner may know water chemistry, equipment, and client care cold, but payroll, workers’ comp, liability coverage, and onboarding are new terrain. There is also the human side: telling clients someone else will s...

Black algae has a reputation that matches its look: stubborn, slow to die, and quick to return when ignored. Despite the name, it isn’t a true algae but a cyanobacteria wrapped in a tough biofilm that shrugs off normal chlorine levels. That shield is why you can hold 5 ppm free chlorine and still see the same dark, coin‑sized spots stare back from plaster or Pebble Tec. The organism wedges into tiny pits and micro‑cracks, anchoring itself deep enough that a casual brush only takes off the “head” and leaves the root behind. If your pool surface is aging, etched, or cracked, expect more colonization and more frustration. Success starts with understanding the biology, then matching it with treatments that expose the cells and keep pressure on them for long enough to make a real dent. The first critical move is mechanical: break the biofilm. A small 5‑inch stainless steel brush gives better leverage than a wide one, letting you attack each spot with force. On fiberglass, avoid stainless an...

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. Older...

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...
