Flowclear Polysphere Filtration Filter Material for Above Ground Pool Sand Filter Pumps

Easy to fill and refill the pump and filter. Cleaning is simple and certainly good to use. First fill lasted 6 weeks before needing to change. One box should last the full season and every chance into next summer.

They work great & you don’t even use them all. Bought at end of season so not really got ti try fully yet until next year now.Word of warning though… don’t touch the balls! I stupidly did, & didn’t wash hands. A while later I must have touched my lip & the taste was awful & it stayed for ages!!

Thought I'd give these a try as some reviews were good. However these are one of the worst things I've bought. I have the 12 foot best way framed pool and these did nothing.

I would not recommend the balls instead of sand.They cannot cope with a slight amount of algie. They have been clean washed a day before and yet they can't keep up with keeping the pool clean, despite all of the chemicals limit are good.We have 15ft pool and the pump runs all the time.
