Yoooo. I saw the sticky concerning bio-media and i know for the canister media it said the surface area varied. But can anyone give me a number so I know where it stands agaisnt the other types of media given in that sticky? Also, I put more of the marineland cermaic filter rings for the biological purpose. How long will it take bb to colonize on the new bio-media? And my 10g is already cycled if that helps. Thanks guys.
