Have had these in my tanks for years..as they help with the water clarity. think they are worth the investment and they last long enough that they are budget friendly over the long life of the product.

I have a 29 gallon tank with a Cory catfish and a Huge plecostomus that was really getting funky. Despite using liquid chemicals that are designed to solve the problem, as well as partial and even complete water changes, it would get smelly soon after. I put 4 of these blocks in as a last ditch effort and I can finally walk past my tank without having to hold my breath.
