1.5 lbs Pool Filter Balls Media Filters Environmental Protection Filter Media for Swimming Pool Aquarium Filters Alternative to Sand(1.5 Lbs Filter Balls is Equivalent to 50 Lbs Filter Sand)

Prior to this product, I used pool sand in my Intex filter. Tried this for the first time this summer season and it worked great.My Intex pool filter has a center stem (plastic stick) that goes into the tub and tells you how much sand to pour in - did not use that (no longer need). From this new filter balls, I only put in about 1/4 of the bag and it worked fine. I went 7 wks before opening this to clean (which is too long; probably should clean after 3 wks). Water was dirty and the filter balls where stained. I washed and rinsed them out several times and it was all good. One filter ball was extremely dirty and stained, so I just threw that one out.Very happy with the purchase and very happy I do not have to store half-used bags of pool sand.

I switched to these and got rid of my sand. Quality was fantastic, the price was even better. Hands down the best decision to change from sand to these.

Is this better than sand?I'm not sure as we did not use sand with our first sand filter pump set up. We went straight to these filter balls. So far so good!Pool is nice and clear.Moving the sand filter around is easy as it's not as heavy.You can not "flush" the filter balls.Once a month we simply unplug the filter pump, remove the filter cover and put all the dirty balls in a mesh sack and rinse them with a hose until they are white again. Rinse out the filter housing and put the balls back in, cover back on and we are set for another month.

The media could not be loaded. Ever since I replaced the sand in my filter with these pool balls for filters my pool has been working better than before. They are easy to use, the price is great and the appearance looks like regular cotton balls but they are not! I will be purchasing them again

Last pool season we fought sand being pumped back into our pool and were not as happy as we thought we’d be with our sand filter. But this year with the cotton balls?!? No sand on the pool floor, no algae EVER, crystal clear water all season long! We’ll never put sand in the sand filter again!

These filter balls seemed to do a decent job of filtering. Once the pressure increased on my filter gauge indicating the filter was clogging up with debris, I backwashed the filter balls for several minutes. The backwash water did not look dirty which means very little of the trapped debris flushed out of the filter balls. The filter gauge measured a decrease in the filter tank pressure after restarting the pump on "filter", but the pressure reading was much higher than when the filter balls where first installed. That confirmed to me that the filter balls were not fully flushed out with backwashing. Pool water chemistry was good, but algae began to grow. After shocking the pool water to killing the algae and then running the filter pump 24hrs a day to clear the water, cloudiness in the water reduced, but never went away completely. Then algae started to form again. My trusted pool supply person who has been helping me monitor the chemistry said, "I think the filter media isn't doing the job." I replaced the filter balls with sand and the problem has not returned. The only thing positive I can say about these filter balls is that they are easy to remove from the filter tank when I switched to sand. The time window to return the filter balls has past, so I guess I'm stuck with the dirty balls.

I’ve always had a sand filter, this year I had a smaller pool so I decided to give these a try. Clean pool all summer! When I drained the filter I tossed the balls in my washer and then the dryer! Perfect! Ready for next summer!!!

I loved the idea of these. No lugging sand?! Great!! But less than three months after I started using them, they weren’t cleaning and no amount of backwashing and rinsing helped. I had never seen any dirty water come out of the backwash valve so I figured the dirt was remaining in the balls. And it was. I ended up removing them and replacing with sand which wasn’t as bad as I thought. Fifty pounds in a compact bag isn’t too hard to move around.
