What size tank?

[bigred]

I'm going to build a inset in one of my closets so the tank will be seen from the other side of the wall in the hall way. My closet opening is 5 ft wide. I want to build a reef setup. How many gallons would it be for a 5'x24"x18"? I was also thinking of doing a 135 gal but I don't think it would fit through the closet opening because its 6' long.

You could put a 120gal in there. They make them 4*2*2=120gal
the formula is LxWxH/231=gallons..
I would get one that is reef ready and put a sump on it. That is a good idea putting it in a closet. Easy to do maintance that way..
There is a company out there that makes a 5' 90 gallon too. I don't know the name of it right off the top of my head. If I think of it I will ley you know. What type of lighting are you going to use? You need to be carefull with heat in a closet.
