Minis - Filter Media - Made in The USA, Easy to Install Filter Media for Above Ground Pools - Replacement for Sand, Zeolite, and Mystic White - 1/2 Cubic Ft. (Pack of 5), Color May Vary

The CBL supplied media is better - I have been using Filterballs for three years now and although I have mixed these with the larger type in many filters, and have recently mixed them with CBL type, they are expensive.We use these in a professional environment and they are good, but Filterballs really do need to look at their pricing structure to be cometitive...

Our 33 foot round PermaSalt pool was installed in 2010. It was time to replace the latterals and sand. I decided to give FilterBalls a try. So far they are working great. It is so nice to not have to deal with heavy sand. My pump is a single speed 1.5 HP pump and it seems to be working fine with the FilterBalls.

Excellent customer service and even better product. Crystal clear pool all season!

These filter balls are amazing!!! After doing some quick research about using filter balls in place of sand, I purchased some filter balls on Amazon and in less than a month my pool was constantly cloudy noatter what I tried. I hadn't researched enough to realize there was am EXTREME difference between these balls and the off brand I had purchased. When I dumped the off brand balls from my filter tank I found they had basically disenegrated into much and we're stuck in and on everything. I had to take the entire filter housing apart and clean it. My filter is rated for120lbs of sand and I purchased and used all of 3 bags of these mini balls. MUCH better. My water was never this clear using sand. Now I waste a lot less of my time on pool maintenance and more getting to just enjoy it.

I got these 2 months ago when we upgraded to an all-in-one Intex sand filter/pump/Salt cell. So far they're working great, and the real proof is the overall results: our pool water stays clean, clear, and easy to manage.I got an over-sized filter unit for our pool, so under normal use, it only runs about 4 hours per day. The pressure gauge has stayed constant at about 5-6 psi, and when I did my first monthy back-flush, it took less than 20 seconds for the water to run clear.And I LOVE the salt water system! After I initially got the chemistry balanced, I have only had to add muriatic acid twice, and small amounts of stabilizer as needed.

Read many reviews of lots of people liking these. Since it was time for me to replace my sand, I went ahead & purchased 3 bags of these. Had these in my filter for 3 wks almost. Pool was cloudy & would not clear up even after using 5 doses of clarifier. Every time I would back wash with the filter balls, my water would be clear every time but should be dirty as my pool was very cloudy. They were not filtering out any of the particles. I decided to look in my filter & check what the inside looked like since I was not getting good results. There was soupy green water in the bottom half of my filter. Took the filter balls out, replaced with sand again & now my pool is clear finally. I will not try this again..

Pool will not clear completely.

I was so tired of my sand filter. I replaced all the parts, added new sand, and my pool still wouldn’t get cleaned. All last summer it looked cloudy and I kept finding sand at the bottom of pool. I found these on Amazon and they actually cost less than the sand. Replaced all of it and in 1 week I could see the bottom of my pool. Truly amazing!! I can’t say enough great things. I haven’t opened my filter yet to see how dirty the balls are, and I’m fine with having to wash them if it means my pool stays clean. If you are tired of dealing with sand, switch to these.
