I got these to test a theory about using the Bioballs to help cycle the tank. I set up two 30 gallon tanks identical setups since I running two new freshwater tanks. I am using a aquatop 400 canister with 2 1unit chem-pure as my carbon in the second stage and bioballs in my third. The second setup has the chem-pure in the second stage but only has the white padding in it. I did add a bottle of bacteria to help with the cycling but after a week the tank with the bioballs has completely cycled as for the tank with out is still ever so slowly cycling. Since then I have no spikes in any of my parameters and wish I would have found these little buggers early. This is a great product....great surface area for bacteria to thrive.
