How many ports do I need for my new custom 190g?
The dimensions of my new tank will be 48"x36x25". It will have 1 overflow centered on the back glass with 1 drain and 2 returns. I was wondering how many ports do I need for a closed loop system? Do I need any other ports drilled for anything else? Also, what sizes? TIA
