Skimming the pool's surface by hand every few days is one of the fastest and easiest ways to keep your pool clean. Floating debris will eventually sink, becoming harder to remove. Use a long-handled net called a hand skimmer or leaf skimmer to remove leaves, bugs and other unwanted items. Skimming significantly increases the efficiency of the pool's circulation system and lowers the amount of chlorine you'll need to add to your pool. Cleaning out strainer baskets at least once a week also helps circulation and lowers chlorine demands. Locate strainer baskets attached to the side of aboveground pools and in the pool deck of inground pools. Simply remove the plastic basket and shake it out; spraying the inside with a hose can help dislodge stubborn objects.
