Those stuffs are just for show. lol. Everything will go downstairs. I build the stand big is for when I need to downsize and keep everything in there.
I'm gonna use a 75 gal as the sump. With quite a few clipon fans blowing at it. Right now the fans in my living room blowing at the tank is just way too loud. Also like to run a big algae scrubber. I need a lot more room than the stand has. After I move all the pumps and skimmers and stuff downstairs, the living room will be like a living room again. Right now, it sounds like a fish market. lol
