Lark Filter Balls - Starter Pack

Make sure you keep your pool safe and clean with the Lark Filter Balls, now in a convenient value pack. The ultra-fine, heavy-duty filter paper ensures dirt and debris does not get recirculated back into the pool. Replace every couple weeks (depending upon use), giving you the time to enjoy a refreshing summer all season long. Universal Compatibility: Whether you have an inground pool or an above-ground swimming pool with a sand pump, our pool filter balls for inground pools and above ground pools are designed to fit most pool filtration systems, ensuring compatibility and efficiency. Low pressure yields in the filter tank. Unlike Sand filter that filters the debris several inches on top of the sand bed and requires back wash every week, Aqualoon catches the debris on each ball and requires no back wash the whole season, means lower electricity bill and water bill Light weight, 1.5 lbs Aqualoon equals 50 lbs of sand
