I have already bought my new tank. It is a 125g All glass. I am doing a center overflow, and will drill 4 drains in the back. The sequence barracuda is going to push about 2750GPH at the 12ft head I am going to run. My drains will be 1.5".... rated approx 1000 gph ea, I shouldbe fine... but am still considering dividing the sump to minimize any chance of a flood. I figure the pump chamber of the sump will only hold about 20g... that way,... if for ANY reason... My drains slow down, or get plugged, or anything else, only 20g will be pumped from the basement into the tank. It is basically the same type setup I have on my 55g, (with the CPR) and it has kept water off my floor several times.. I know it is a very small chance that something could restrict my drains enough to cause a problem... but Im not willing to leave myself open to 150g of SW on my floor, however small the chance.... because with my luck... it would happen...I am also poking two more holes in it to run a sequence dart CL... I should end up with about 4000gph flow... I HATE the look of powerheads in the corners of the tank.... and this way, there will be no need for any...
