alright so i am planning on upgrading from my 55 to a 75. When i built the stand for my 55 i had to make it bigger then the tank to have enough room for my sump and everything underneath. The stand is long enough for a 75 but from front to back it is 18" and a 75 gallon is about 18 1/2 "will it be alright for the tank to hang off the back of the stand about a half an inch?
