The Flow clear 680gallon Skimatic Filter Pump is a filtration system combining a surface and water skimmer - with no extra hoses needed! This innovative pump by Best way is simple and easy to install in your above ground pool - simply plug it in, hang it over the edge of the pool, be sure it is immersed in water and watch as it starts to go to work cleaning your pool! Plus, it works silently - no more noisy pumps! The Skimatic filter pump has a large capacity tank that sucks in floating leaves and other debris, keeping your pool water fresh and clean. The Skimatic can be cleaned with a water hose daily - just be sure you have it unplugged before you do any maintenance on the pump. It utilizes #58012 filter cartridges by Best way, which we recommend changing every 2 weeks for optimal use. For use with 300-5,400 gallons pools. You will love your Skimatic Filter Pump! Not recommended for use on Steel Wall Pools.
