Hey all, just wondering about some pros and cons of the HOB
overflows and drilled tanks. Also, experiences and tips on how to make my own if the drilled tank part it better. The tank is a 180 gal
that I would like to be a reef. ( if all this money I'm spending and racking my brain so much doesn't kill me. ) haven't decided what size sump yet. Would have loved to have a four foot but the support beam in the bottom of my cabinet tells me otherwise. Unless there is a way I can safely lift it just above the support beam. Thanks in advance.
