i have a 10 gallon tank that already drilled with 3/4 inch holes on the side. the bottom has enough room for a 5 gallon tank or really tall but skinny tank. and it can all be plumbed in the stand.
i really just started this project to keep me busy. i already have my 35 hex i dont need another tank. and if this one sells il just start another stand and hood. but if it doesnt sell il set it up.
