Hey all! I want to enter the nano in 90 competition but I am VERY low budget...the only real expense on equipment will be a light and a powerhead. I have a 20 gallon tank and a HOB for it. Is it ok to run a nano with a HOB? It will contain a small bag of GFO and carbon. Let me know since I have never had a nano tank and want some advice. :tongue:
