I have used this for years in my Cascade canister filter for my 75 gallon planted tank. Great for aerobic nitrification and a great all around biological media. Keeps my tank algae free and water crystal clear.

This product delivers as advertised . With regular water changes and cleaning the canister, my nitrate levels have gone down. I have a 55 gallon tank with one Oscar and a Amazon catfish.
