Hey everyone I figured I would start a thread on what goes into the hobby from the start. I want everyone to help we can setup a tank and see how it progresses! Let's all throw out some ideas and as a club throw together a bigger nano tank that all in one. With that said what's the first thing to do after I bought a tank? I got the fluval eco 13.5 gallon peninsula tank. Looks like it has a light, and return pump not sure what else. What do we need now!
