Oh btw, anyone else trying to do a sps nano tank, any suggestions would be great. My biggest issues are nitrates, with a natural fuge and GFO. I just put inline some biopellets so we'll see how that helps. The other issue is trying to find the perfect settings for my new AI Hydra lights. A shallow and longer tank definitely creates some lighting obstacles. I'm actually thinking about building a floating canopy with the Hydra and a T-5 retrofit kit integrated. Comments and suggestions are much welcomed
