Pool Care

For most chlorine pools: Free Chlorine 2-6 ppm (the correct target depends on CYA), pH 7.2-7.8, Total Alkalinity 60-90 ppm, Calcium Hardness 200-400 ppm, and Cyanuric Acid (stabilizer) 30-50 ppm. Key point: chlorine targets only make sense when paired with the stabilizer level. Low CYA with high sun burns chlorine off fast; high CYA requires a higher chlorine target.

Beach-area pools typically deal with more wind-driven debris (sand, pollen, salt spray), higher corrosion risk from salt air, more UV and weather swings causing faster sanitizer loss, and more algae pressure in season. This means coastal pools usually need tighter consistency in cleaning, filtration, and chemical control.

Weekly: Test and adjust FC and pH, empty skimmer and pump baskets, brush and skim, vacuum as needed, and do a quick equipment check. Monthly: Test and adjust TA, CH, and CYA, confirm salt level if saltwater, inspect filter condition, and check for early failure signals like air bubbles or recurring cloudiness.

Chlorine and pH are only the top layer. A pool can show 'good' chlorine and pH and still have problems caused by high CYA (over-stabilized water where chlorine becomes less effective), wrong TA/CH balance (causing cloudiness, scale, or corrosion), or filter/flow issues. Chlorine and pH are necessary checks, but not sufficient control.

Yes, if you want stable water and predictable chemical demand. CYA controls how much chlorine you actually need for sanitation. TA stabilizes pH. Too high drives scale and cloudy water, too low causes pH bounce. CH protects plaster surfaces and reduces corrosion risk. If you only test chlorine and pH, you will eventually get 'mystery problems' that are not mysterious at all.

'Shock' is not a fixed schedule. Use it when conditions justify it: after a heavy bather load, early algae signs, or storms. For most pools, maintaining proper daily FC for your CYA reduces the need to shock routinely. Swimming is generally OK when water is clear, FC is back in the normal target range, and pH is 7.2-7.8.

That 'chlorine smell' is often chloramines, not 'too much chlorine.' Causes include low effective sanitizer, poor oxidation, and heavy bather waste. Fix by verifying FC and CYA with a reliable test method, raising FC appropriately, improving circulation and filtration, keeping pH in range, and reducing contaminants by showering before swimming.

Do not do that. Tablets are acidic and can sit concentrated in the plumbing, which can damage pump seals, heater components, and valves and fittings. Use a proper feeder, floater, or a safer, controlled dosing method. If chlorine is critically low, address the cause (low output, high demand, high CYA, or filtration).

In summer, typically 6-10 hours per day (more if you have heavy debris, high bather load, or a salt system that needs runtime to generate chlorine). In winter for non-heated, low-use pools, often 2-6 hours per day. The better rule: run long enough to keep the surface clean, the filter pressure stable, and your sanitizer consistent.

General rule: clean/backwash when filter pressure rises about 8-10 psi over clean starting pressure. Sand filters: backwash at +8-10 psi, plan sand replacement roughly every 5-7 years. Cartridge filters: clean at +8-10 psi, replace cartridges commonly every 2-4 years depending on use and care.

For most residential pools in-season, weekly service is the baseline for consistent water and early problem detection. During cool months, some pools can step down if use is low and debris is manageable, but chemistry still needs monitoring. Most damage to pool surfaces occurs during the off-season due to improper water balance.

Typical weekly service includes: water testing and chemical adjustments, skimming, brushing, and vacuuming as needed, emptying skimmer and pump baskets, filter and circulation checks, and notes on developing issues before they become failures. Exact scope can vary by package and pool condition.

Yes! Chemistry-only service is a fit when you want to handle physical cleaning but want a pro managing testing, dosing, and stability. Chemistry problems are where most DIY pools get expensive fast. Improper balance can damage surfaces, corrode equipment, and lead to algae outbreaks.

For many owners, yes. The value is not just labor. It is consistency and early detection. Typical benefits include stable water with fewer algae and cloudiness events, fewer equipment failures from unnoticed warning signs, less time spent testing and troubleshooting, and better overall pool condition. DIY can work if you are consistent, use reliable testing, and understand CYA-driven chlorine targets.

Yes. Openings focus on cleanup, equipment startup checks, and chemistry stabilization. Closings focus on cleaning, protecting equipment, and setting water conditions to reduce off-season problems.

Yes. The fundamentals are similar, but uncovered pools usually need more attention to debris and water condition over the off-season. Covered pools often stay cleaner but can still drift chemically.
