I am in the middle of setting up my first saltwater tank. My tank will be 72 x 24 x 24 (180 gallon) I feel i have done a lot of research but still cant find what i am looking for. I know everyone tells you to put as big a sump in as possible, but inside my stand i only made it 27 inch tall because it is going right next to my couch in my living room i want to be able to look in the tank when i am sitting next to it and i also wanted to make maintenance ez on me, as i have a freshwater tank that is 28 tall on a stand that is 28 tall and this makes water changes harder unless you use a stool witch i do not like to do. When you factor in the bracing i used i am left with a space 60 x 21 x 26 and. My Question is will a sump 48 x 18 x 18 be big enough i want to put a refugium, skimmer and all equipment in there as well or should i remake to stand bigger so i can fit a bigger sump? Just thinking i should have made the stand 24 wide on the inside and also is this to short for a stand? I am trying to do this right and take my time and advice would be greatly appreciated.
