I am getting a new 225 custom glass tank but need help with where to place the 2 external overflows, returns and holes for a closed loop. Also how big should the holes be. I am planning on a 4" dsb so I assume no holes until 5" + off the bottom?
The tank is 72L x30W x24H
I am replacing a failing tank and would like to do things right this time so any help will be welcome.
Thanks
