Works better than sand

I was loosing pressure with my water flow so I decided to get rid of the old sand and give these a try. Best decision ever. In one day my water went from green to crystal clear.

This is my second time buy this type of filter balls. We were having a problem with our pool sand channeling and it blowing the sand into the pool. Ever since I bought these we have had no issues. The first ones I bought were white and lasted roughly 3 seasons. At the end of the season I remove them from the sand filter, put them in the bags they provide, wash them out really well and set them out to dry. The only reason I replaced them is that they had lost their shape and we getting a bit gross. I hope this new design works just as good and last as long as the first ones.

Loved these as a replacement for the heavy sand in our above ground pool filter. It is useful to buy enough to allow for a replace and wash. The pool stayed clear!

These are a great replacement for sand filters. Nice not to have to change the sand every couple years. Just take out throw them in the washer and they’re ready for next season. I’d highly recommend these.

100% better than sand.

Terrible product. They just dont work. Tried the balls for 1 week and the pool was still green. I switched back to sand and the pool was blue in 1 weekend.

I used these for a full season and we are going back to sand next year. These balls filter debris much better than expected but turned my water blue because of all the blue fuzz. We also experienced episodes of cloudy water which caused us to use much more additives then we ever had to with sand.
