I have 2 230g tanks and a 90g sump. My next step (possibly) is to change out the 90g sump to a 300g sump and we might change the reef 230g to a 300g ish tank 6 feet long by 3 feet wide and 2-2 1/2 feet high. Instead of that though I'd rather get a contractor in and set up floor bracing for the front living room (which is large) and set up a 10 feet long by 3 1/2 - 4 feet wide and 2 1/2 feet high.
The not so realistic would be to move into a different house with a large open basement and set up a 10 feet long by 10 feet wide and 3 feet high.
Doubt I'll be doing anything anytime soon though. Unless my friend changes out his 300g sump and wants to sell it to us
