Hey guys. I am currently running a little 40 breeder reef (been running for a month or so right now)
Well today I came across a great deal, and picked up a new acrylic 120 gallon with stand and skimmer.
The overflow is already installed in the center, but not drilled.
I am going to use my 40 breeder as the sump..
My only question is, what size bulk head do I install when I drill a hole for the overflow to sump? Also, I need a return pump. How many GPH
do I need? I have never dealt with sumps so I am totally new to this. Any info would be awesome.
Also, the overflow will flow directly into the large skimmer in the sump and will recirculate, and output back into the sump.
