Hydro Life 52804 Pool Pre-Fill Water Filter with Calcium Blocker

Hydro life Pool and Spa #3 Calcium Blocker filter is designed to be used on your water source as you fill or top-off your pool. The filter media is specifically designed to reduce the levels of calcium in source water, as well as effectively reducing levels of heavy metals, chlorine, chloramines and volatile organic compounds, which helps make balancing chemicals easier. It also pre-filters stain causing metals before they have a chance to damage your pool or spa. This easy-to-use filter connects to any standard garden hose and filters up to 10,000 gallons of water, depending on the quality of the water.
