Hi everyone I posted a few weeks ago about a sumo and decided to do this I am running a 75 gallon on a canister filter was going to do a hang on the back overflow but decided to upgrade to this 135 gallon. It’s pre-drilled as you can see in the picture and the stand doesn’t really suit to have that big of a sump the biggest sump I can put in there is my 20 gallon long that I made with baffles that I was gonna put below my 75 if I go any higher then I won’t be able to take my skimmer out if I need to do any maintenance or if there’s a malfunction. The previous owner of the 135g drilled the floors and had sump in basement I don’t have that option. Anybody have any ideas? There is also a picture of the stand so you get an idea.
