Make sure you use some kind of auto drip system with an overflow.. that will make your life 10x easier.. and almost maintenance free. What kind of stock are you planning to keep?Now I have to design the filter room. I have 30" behind the length of tank for maintenance and a 6' X 10' room to the right of tank for the filter room. I want it to be as maintenance free as it can be. I'm going to have a 120 grow out in there, central sump, auto drip, etc. The filter room design is what I need help with. Any suggestions appreciated...
