Hey ho,
Here is the deal.
My 130g tank has 3 holes drilled into the bottom. all are 1". I was thinking that one could be a drain to my sump (with a pvc riser) but, this only gives me a 5/8' drain hole once the bulkheaad pvc is installed. While it will drain a little, I am wondering if it will be enough!? Could I use two of the holes? and the third as a sump return? ( I would rather not as 2 feet of pvc riser is quite ugly and the first one is in the back corner and easy to hide.)
