Check circulation and visible condition
Look for leaks, unusual pump noise and changes in filter pressure. Check the skimmer and pump baskets according to the equipment manual. Do not open pressurized equipment while it is running.
Remove debris and clean surfaces
Use a leaf net, brush and cleaner suited to your pool surface. Inspect brushes and cleaner components for wear, and keep debris away from drain openings.
Test the water
Use a suitable test kit or test strips and follow the kit instructions. Check the measurements relevant to your sanitizing system and water conditions before adding chemicals.
Follow the product label
Chemical dosage depends on the measured water condition, pool volume and product formulation. Follow the product label and local requirements. Never mix pool chemicals together.
Keep a simple maintenance record
Record test results, cleaning dates and equipment changes. A consistent record helps you identify changes in circulation or water quality and decide what to inspect next.
