Flowclear Pool Filter Cartridge Polysphere Filtration Balls

This wasn't part of a promotion- had trouble w sand leaking into pool. Tried sand %26 glass both no luck. These are great! No more spills from filter. At first I was sceptical but I'm sold now.

I love these polysphere filter balls. Although recommended for a sand filter I have cartridge filter pump. I made a little screen out of chicken wire, or you can use a regular screen from a window, so they don't get lost or sucked through my hoses and put the balls in instead of an A/C cartridge. They work fantastically!!! Helps clean the pool faster than the traditional cartridges. I would highly recommend even if you don't have a sand filtering pump.

We were amazed how clean and clear our pool was all summer!! So much better than sand, so glad we discovered these.

These balls work great in our filter. We don't use sand at all. They also work great in our hot tub filter. I would recommend them to anyone.

The quality is really amazing and the price insanly good for the same amount and brand on amazon it costed 33$ but walmart 9.98 i literally saved money and i really needed this for my pool so thank u

I dumped out my sand out of my filter and washed it out. It was a little bit of work, but putting the cotton balls in was a piece of cake. It took the green out of my pool overnight. I've barely had to backwash, and I am very very satisfied. Nothing is getting clogged. I open my pool this year and didn't even have to vacuum it. These things are awesome. I have a 21 foot semi inground pool with a Hayward sand pump and filter

It works ok for our Sam's Club pool. The original balls were stiffer/compact and worked well for dust. These do not keep the water clean of dust.

Nope, don't waste your money. They are cotton balls on steroids. I had to buy another bag of filter sand.

Never ever in store. App yes in aisle 12, but NEVER HAVE I FOUND THEM. Even with employee help. This is a HOT item in the summer too

I have only used these for 3/4 weeks. I backwash %26 rinse OFTEN! My pool was not holding chemicals or staying clean what so ever! I decided to drain half my pool and open the filter to see how the filter balls looked and they were TERRIBLE and so disgusting. 10/10 DO NOT recommend these. For sure a waste of money.
