Keep crystal-clear, clean water flowing through your above ground pool with the Flowclear™ 3000 gal. Sand Filter Above Ground Pool Pump! This powerful pump systematically processes 2,200 gallons of water per hour, and is compatible with most 300 - 17,600 gallon above ground pools, as it comes with an adapter for pool valves with an outer diameter of 1.5 in (3.8 cm). Our ChemConnect™ dispenser, also included, provides a stable level of chlorine throughout your pool to maintain clean, healthy water and proper chemical balance, giving you two efficient tools to keep your pool in tip-top shape year-round! With its pre-filter strainer basket to catch large particles such as leaves and sand to capture finer materials such as hair and dirt, the Flowclear Sand Filter Pump's durable, corrosion-resistant filter tank runs smoother and longer than traditional filter cartridge pumps. Simply add your own sand (approximately 79.4 lbs; not included) or our highly-efficient, cost-effective Polysphere™ pool filtration spheres; quickly install the preassembled pump and adjust the 6-position valve for easy, low-maintenance filter control.
