biocube 29 overflow

[mofishman]

Is this possible on a BC29? Could you run the overflow out from chamber 1, and return to one of the other chambers? Problem is making a overflow that will fit in that small of a space for it to work. Thoughts ideas?

I drilled mine. Drilled two hole from chamber 3. I used a 3/4" bulk head but I run a closed loop you could accomplish the same thing with a dorso or other style drain pipe. I return the water straight back into the display throw a second hoel in chamber 3 and tubing going to the factory return. Hope that makes sense. Drilling is much cleaner. I ran a sump on it for a while as well via the same holes. I used a mag 3 for return and it was perfect.
