As you know... I bought the tank used and it came with a sump (pictured below)... very plain... just one small baffle.
Drilled the hole. (it took two Ryobe batteries) Jonas at the lfs loaned me his hole saw. As they cost a fortune once you get above 1.5 inches.
I wanted to keep it pretty simple but, different. I wanted to have two open chambers... one for the skimmer, (ASM G4X) and one for the 3 HOB phosban reactors. I have set it up so that the majority of the water will be directed to the skimmer side.
