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:

I don't think it's the 70 however...I believe it's the Aquaclear 30? I was going to supplement with a powerhead for flow so I'm not sure if I would need the Aquaclear 70 (trying to use what I already have). However, I do have an aquaclear 50 on my 20H FW planted tank that I can switch to the 30.
