A clean pool is mostly a routine. Testing the water, keeping the filter clean, and running the pump long enough prevent most problems before they start.
Weekly tasks
Test the water for chlorine, pH, alkalinity, and stabilizer. Adjust chemicals according to the test results and the manufacturer's instructions. Brush the walls and steps, skim the surface, and empty the skimmer baskets.
Check the pump pressure and clean the filter when it rises above the normal range. Run the pump long enough to turn over the water, especially in hot weather.
Water chemistry
Keep the sanitizer in range, the pH balanced, and the alkalinity stable. High stabilizer can reduce chlorine effectiveness; low stabilizer lets chlorine burn off quickly.
Do not mix chemicals, and store them according to the label. Add chemicals to water, not water to chemicals.
Seasonal opening and closing
At opening, clean the pool, check the equipment, and balance the water before swimming. At closing, clean, balance, and winterize according to the climate and pool type.
In freezing climates, protect the pipes, heater, and pump. A freeze can crack equipment and plumbing.
Equipment checks
Listen for unusual pump noises, check for leaks, and inspect the heater and filter. A failing pump or heater can cost more to run and may damage the pool.
If the pool is losing water, a leak detection test may be needed. Evaporation and splash-out are normal; a consistent drop can indicate a leak.
Frequently asked questions
How often should I test pool water?
Testing several times a week during swimming season is common. Heavy use, rain, and heat can change the chemistry quickly.
Why is my pool green?
Algae growth is usually caused by low chlorine, poor circulation, or unbalanced water. Treat the water and check the equipment.
Can I leave a pool uncovered in winter?
It depends on the climate and pool type. A cover reduces debris and heat loss, but the pool still needs winterizing.
