Very Good Bio-filter Material

Very Good Bio-filter Material
I just set up a new tank and I'm using this in my hang-behind canister as a bio-filter for the first time. I like it allot. It has a texture that should be advantageous to bacteria growth - some of the best I have seen. Being completely round and as porus as they are, there should be maximum contact and growth with the water.The tank is fishless cycling and the ammonia digestion has really taken off: The tank is completely consuming 4ppm of dissolved ammonium chloride per day and I attribute this to the Eheim Substrat.Eheim products are generally expensive here in the US, many of them are over-engineered, and that often makes them subject to less than stellar performance, but this I believe they hit the nail right on the head.How much to use?As much as you can get in.Hope this helps.
