    This is the best Biological Filtration I have ever used. It cleared my 65 gallon tank very fast and an added bonus, you don’t have to replace it. I have used a few different brands ceramic filter media in the past and as is wore out it would leave a cloudy film on the water surface in the tank. I purchased three 250ml for my fluval FX4 canister filter and it’s working like a charm!

    I have only had this for a month or two, but after destroying our tanks eco system during an attempt to get rid of snails, it has been amazing. For several months, the ecosystem was struggling to cycle correctly. We lost several fish, one at a time, until this purchase. Since adding the Seachem Matrix, the water is clearer, the fish are more lively and colorful. Overall its a great product and maintenance is easy, just rinse rocks off and reuse.
