I have been tossing this around for a while. I wanted to add a sump/ refugium to my 13.5 fluval nano tank. With the stand I have, I can only put a 5 or 10 gallon tank underneath. On my tank the compartments are small and I would like more stability in my tank. I really don't want to drill this tank. I am dealing with a compartment that is only 3"x 4". The other problem is my return runs thru this area. I guess if I had to, I could patch that return and move it to the second compartment. Any thoughts or ideas would help.
