A skimmer basket is a small, removable basket that fits into the skimmer of your pool. The holes in the basket are small enough to act as a sieve. The water continually flows through the basket carrying the tiny bits of debris that find their way into the water. The skimmer hose can be used as a vacuum to pick up sand and small bits of debris, but avoid trying to vacuum larger pieces as they will clog the system and possibly damage the motor. Check your skimmer basket regularly and empty it at least once or twice a week.
