Hello Everybody
I am in the middle of plumbing my fish tank after a move and have a question. The tank is 180G (72 x 24 x 24) with 2 megaflow overflows. The standard 1 inch drain and .75 inch return. I have drilled the back of the tank to have 1 additional bulkhead that would be used as a Herbie overflow. The standard 1 inch drain would be the emergency drain and the .75 inch return would be the same. So the tank now has 6 total holes.
What are your thoughts on connecting the two 1 inch Herbie overflows after the gate valves together to a 1.5 inch PVC pipe that would then run to the sump? The sump would then have 1 1.5 inch drain instead of 2 1 inch drains. I have read that a 1.5 inch PVC pipe can handle more water flow than 2 1 inch pipes.
Thanks for the help
Randy
