Building an internal overflow for my tank. I have a IWAKI MD70 pump about 9' below the top of my tank - 1-1/4" line. Not sure what my actual GPH will be - But I want to get the overflow right the 1st time.
Planning on a corner unit 4"x6". What size slots are needed in the top of it and how many?
1" Durso planned for. Extra 1-1/4" bulkhead in the back if I need more.
