I know that it says 180 plus but I can't find anywhere else to get good info on larger tanks. I recently recieved a 125 gallon tank in trade for a case of beer. It is 18 x 20 x 72. I plan on DIYing mh's for the light system and I have 2 thirty gallon tanks that I can build into sumps/refugiums. My dilema is that I want to do this without drilling this tank. Is it possible or should I just go for it and drill it? Then where and how should I drill it? I am trying to do this and spend as little as possible. But don't we all? Any suggestions for system setup will be appreciated here.
