Premium Sand Filter Media - 150 lbs for Pool, Spa & Water Filtration Systems - High-Quality Silica Sand for Clean & Clear Water

This is my 3rd time I replaced my filter media with ZeoSand. It lasted about 5 years (as advertised) the last two times, and I live in Arizona where the water pump/filter run year round. Once established it gives EXCELLENT water clarity, blocking as i recall down to 5 microns, with sand at 20-100 microns depending on the sand. Shipping agitation will cause the Zeosand to create some dust in the bag. Make sure that you have water in the filter before placing the Zeosand in the filter, and back wash it at least a couple times before filtering the pool water. Zeolite has a light gray/light green look to it. Even with the backwashing you water may show a green tint to the water once you start filtering the pool water. DON'T FREAK OUT, like a number of pool owners do. It just means that there was still dust in Zeosand even though you backwashed it a couple times. Let the pump run continuously for 2-4 days and the water will be crystal clear. Great product.
