    Closed loop help

    I’m getting ready to do a closed loop on a massive reef tank. This tank is 20’ long by 4’ wide. I drew up a diagram on the computer of how I’m thinking it should be, hopefully you can understand it. I wrote next to everything to tell what it is. If you see anything you would change please let me...
