We are thinking of setting up a 20 gallon frag tank from what we have laying around. What we dont have though is the appropriate lighting fixtures to do so. When we went to a hardware store the other day we noticed that they have everything you need to construct your own regular flourescent fixtures. Is there anywhere you can get these same parts for a T5 fixture and would this be aquarium safe? If we can find everything else the only thing im not sure about is if they sell reflectors or where we can find one. What do you guys think? Has anyone else tried this?
