Yup....I won't be doing it again....but if I did, I would go 6 foot square. With a strong acrylic tank, you can crawl around on top of it easily to access anything you want. I didn't know that at the time, so I limited myself to 4 feet of depth.

^^ You wouldn't do a 4foot depth tank again?

My "dream" build would be a 7x5ft or 8x4ft.. but if 4ft is that bad for you, makes me wonder if I would like it... :neutral:

if i do build the 72x72 ill be getting it built in the house unless i do go acrilic, it will be a shrak/grouper tank so ill have minimal amounts of rock i think more like a public display with fake stuff even though thats a little fruity

48" deep
 

My tank is 4 feet front to back...It took some time to get used to but I wouldnt have it any less now that I've seen it...

To get it into perspective, imagine a sheet of 4x8 plywood...Then imagine that sheet of plywood being 3 feet high...Thats the dimension of my tank...

Welcome to Canreef kem.. :biggrin:

The room is 10' wide by 12'-4"deep. I think 8' wide is a nice size, and I don't wont to go over 32" tall. Because its hard to reach the bottom.
At 8' wide I would be able to walk around the back and sides of the pool, ah I mean tank. I can go 36" to 60", quite easly.
The plan is to biuld a steel frame out of 1/4" angle and drop glass in or pylwood with fiberglass. I should be able to put plank on top to lay on to work in the tank. I just have to think light thoughts.
