Swimming Pool Tips and Reviews

Manual pool vacuuming should feel straightforward: connect the vacuum head and hose, plug into the skimmer (or a dedicated suction port), and watch debris disappear. When you get no suction or very little suction, the fastest wins come from verifying basics that affect water flow. First, confirm the skimmer is actually pulling water by looking for a clear swirl into the suction hole, and use caution if you test by hand because strong suction can hurt fingers. Next, read filter pressure (PSI) at the gauge. High filter pressure usually means restricted flow, which translates to weak suction at the skimmer. A DE filter that climbs well above its clean baseline, a cartridge filter that loads up, or a sand filter needing backwash can all choke the system and make the vacuum feel dead. Variable speed pumps add another common twist: low RPM often equals low vacuum performance. If the system runs at an energy-saving setting like 2400 RPM, suction at the skimmer can feel weak even when everythi...

When a pool “won’t hold chlorine,” the first mistake is assuming it must be a testing problem. In peak summer, weather alone can explain a shocking amount of free chlorine loss. High water temperature, extreme air heat, and a high UV index can burn off chlorine faster than most pool owners expect, even when cyanuric acid (CYA) looks “perfect” on paper. If you keep dosing the same way you do in mild weather, you can watch a pool zero out daily and feel like the chemistry is broken. The fix starts with accepting that chlorine demand changes with the environment, and your pool maintenance routine has to flex with it. Cyanuric acid sits at the center of the problem because it both protects and limits chlorine. Too little CYA means the sun tears through unprotected chlorine, especially after a big dose of liquid chlorine or shock. A pool at 20 to 30 ppm CYA may only effectively protect a small portion of your chlorine, so big boosts can disappear within hours. Too much CYA creates the oppos...

Pool service problems often look like “mystery chemistry,” but the real cause is usually homeowner habits that block circulation, contaminate water, or slow down maintenance. One of the biggest pool maintenance issues is low water level. When the water drops below the skimmer opening, the pump can suck air, lose prime, and stop moving water. Poor circulation invites algae, cloudy water, and constant chemical demand. Over time, running a pump dry can damage seals, create leaks, and even burn out the motor, turning a small “save water” choice into a major equipment repair. A simple target helps: keep water about halfway up the skimmer or centered on the waterline tile grout.   When homeowners hesitate to add water, it helps to explain the true tradeoff: a properly filled pool protects the pump, keeps the filter working, and makes sanitizer effective because water is actually moving. Some newer pools have a float diverter valve that shifts suction to the main drain if the skimmer...

Pool fill water is one of the most overlooked reasons a new pool startup goes sideways. When a fresh plaster, pebble, fiberglass, or vinyl pool gets filled, whatever is in that source water becomes part of the project, including metals, tannins, and fine particulates. For pool service professionals, the risk is real: staining, discoloration, and customer complaints often show up after the surface is already exposed. The fix starts before the hose goes in. Testing fill water for inorganics and organics helps you predict problems, choose the right filtration, and avoid chasing issues with costly chemicals after the pool is full.   A key point is that metals show up in different forms depending on the source. Municipal water is often treated with an oxidizer like chlorine, which can turn dissolved metals into extremely fine particulate iron that still comes out of the tap. Well water can deliver both particulates and dissolved metals at the same time, which is why a simple “pore ...

Green, brown, or oddly tinted pool water can look like algae, but the giveaway is often what you do right before it happens. Many pool service pros see the tint appear right after balancing water or adding shock, especially before a weekend party. When chlorine oxidizes what’s already in the water, it can “wake up” metals or organics and create a sudden color cast even when the walls are clean. The key pool chemistry skill is separating stained water from a stained surface, then proving whether you’re dealing with metals like copper or iron versus organic material like tannins, humic acid, and other natural compounds from a fresh fill.   A simple diagnostic step can save hours of brushing and wasted chemicals: add ascorbic acid. If a green or tea-brown tint turns crystal clear after about a pound (scaled to the pool size), that strongly suggests oxidized metal in the water, not algae. In that case, treat it like metal staining even though the color is floating in the water: us...

Balanced pool water is not just a “nice to have” for clear water. It is the core defense against corrosion, staining, and surface damage that shortens the life of plaster, heaters, and fittings. Water is naturally aggressive, meaning it will try to reach chemical balance by dissolving what it needs from whatever is available. When calcium hardness and carbonate alkalinity are too low, the water can pull calcium and carbonate right out of a plaster surface, slowly etching and weakening it. With vinyl liners, low alkalinity can even draw out plasticizers, leading to wrinkles and premature liner problems. For pool service professionals and homeowners, using water balance targets and the LSI (Langelier Saturation Index) is a practical way to avoid “hungry water” that quietly destroys expensive surfaces.    A big part of pool water balance is controlling pH and total alkalinity as a buffering system. Keeping pH in the 7.2 to 7.8 range supports effective chlorine sanitation while re...
