I was getting ready to make a diy 20gal long sump for my 55gal, but there is no way the tank will fit in the cabinet. I don;t want to leave out because it would be an eye sore and a pain in the ***. After measuring everything i can easily fit a 10gal, maybe even 15gal tall.
But that means that it would be a small sump, only adding maybe extra 8 gallons to the overall volume. If i put my skimmer/heater/Uv
in the sump, it will not fit anything else.
My questions is, besides hidding all the equipment, is there any benefits of such a small sump?
