After way to much time I finally got my tank up and running. Its about a week into the cycle and the tannins are starting to release. The filter media is in the tank where one final big rock should go because my canister filter is defective and I dont know when Hydor customer service will reply to me. Anyway does anyone got any ideas which could help me improve the setup? I'm going to be building a light setup this weekend with 1 or 2 10w led spotlights as lighting.
