Pool Maintenance Schedule: Weekly, Monthly and Yearly

The difference between an easy pool and a difficult one is consistency, not workload.

An owner who spends twenty minutes a week, every week, uses noticeably less chemical and has fewer problems than one who leaves it a month and then fixes everything at once. Recovering a green pool costs several times what routine care costs.

This is a guide for a typical home pool in Thailand. Adjust it to how you actually use yours.

Every week, about 20 minutes

Test the water, at least pH and chlorine, with a test kit or test strips. Target pH 7.2-7.6 and chlorine 1-1.5 ppm.

Correct whatever has drifted with pH Minus or pH Plus. Always correct pH before adding chlorine.

Add chlorine according to the reading. Long-lasting chlorine needs dosing less often because it holds its level better.

Skim and brush with a leaf rake and a wall brush. Brushing matters more than people think, because algae always starts in corners and grout lines.

Empty the skimmer and pump baskets. Two minutes, and it stops the pump working harder than it needs to.

Every month

Vacuum the floor with a vacuum head, telescopic pole and vacuum hose. Even with a robot, check the corners it cannot reach.

Backwash the filter, or whenever the pressure gauge reads 8-10 psi above normal.

Test total alkalinity. It should be 80-150 ppm. If it is low, pH will swing all month. Correct it with Alkalinity Up.

Top up chlorine stabiliser on an outdoor pool. Sun Block keeps chlorine in the water much longer, especially through the hot season.

Every quarter, or when symptoms appear

Test phosphate with phosphate test strips. If algae keeps returning despite adequate chlorine, phosphate is usually the reason. Treat with Nil-Phos.

Chemically clean the filter. Backwashing alone does not remove oils and fats. Use filter cleaner and degreaser two or three times a year to extend the life of the media.

Test calcium hardness. It should be 200-500 ppm. Too low and the water attacks the pool surface itself. Correct with Water Hardener.

Once a year

Inspect the filter media. Sand wears out, and once it does the water will never be properly clear no matter how much chemical goes in. Consider switching to glass filter media, which lasts longer and uses less water.

Check the pump and electrics. Listen for unusual noise and check the seal for leaks.

Check the underwater lights. If one is dimming or letting water in, replace it before the damage spreads.

What to keep in the house

Based on what customers call about most, these six are worth keeping in stock.

pH Minus · pH Plus · Shock Chlorine · Long-lasting chlorine · Test kit refill · Pool Floc

The reason is simple: pool problems tend to appear when the shops are shut or over a long weekend. Having the basics at home means you can deal with it before it escalates.
