It does if you do it right. Usually the bigger is best. Because the cost of glass. Depends on ur budget. If you already have glass or a hook up then great. I have to go from scratch. I do have a 240 gallon that I cracked( just back glass) so I will probably build another smaller tank using that. You should get an idea of how much retailers are asking for the size you want and price out material. I'm doing a 600 gallon (inner diameter) I am spending money but no where near what I can buy that tank for already built. Do you have any hookups with material?
