Hey guys im building a new house and i would like to build a fishtank in a wall. It will be under the stairs in a closet. I figured if i run a AC vent in there it would help with the heat? I want to do a reef tank. Not a real advandced reef tank some thing like mushrooms and easier stuff like that. Question is i was thinking if i did a DAS tank it would be easier for up keep. What do you guys think? please help with ideas.
