ok, cool, and thank you all for your input. Here is my delema. I am moving in a few months. I have a 120 glass reef now that is doing excellent. Only problem is when I bought the tank my LFS told me I was crazy for wanting 2 drains. So I listened and have one 1' drain(internal overflow). I want more circulation/turnover in my sump than the 1 drain will alow me. Also, I recently added a closed loop system with a SCWD but my tank was not drilled for it. It works great but to tell you the truth- I hate the PVC in the tank.
What I want is another drain added- which will probably force me to remove the internal overflow and install a larger one.
Also I want 3 holes drilled on the back of the aquarium for the closed loop.
This is the delema....Do I try to have this work done on move day which would have to be percise and on time, or should I just purchase a new tank and have all this work done? I would sell my current tank and use the stand and canopy for the new.
What do you think? Is this overboard/crazy?
