I know one of the benefits is that is hides all the equipment and adds more water volume. Although then does it really matter what size your sump is????? Like I have a 55 gallon that is in rough shape and I am thinking that maybe I don't want it to be my sump anymore since I am in a building and a water flood could be serious. I want to buy a ready made sump although most of them come in the 20 gallon range. Does anyone here know where to buy a good quality made sump for a larger tank.
