Rated 5 out of 5 by Tomasz These balls are the best thing I have bought for my tank
Filter Media Balls are better than I had hoped or rather better than I knew. Frankly I was not sure what I was purchasing and I did not change out the old filter balls that I had been using. I simply layered these on the top---a layer of carbon and a layer of ceramic. My water, which was clear but occasionally looking somewhat foggy, is nothing short of magnificent. It looks like the fish are swimming in air.
These balls, both the ceramic and the carbon are the best things I have purchased. And as they are refillable they make great economic sense.

This product is great, fits well with my filtration system. Only thing is., when it's time to change the media, they are a little difficult to open. Other than that, there worth the loot!!
