I need the opinion of the group here if possible. I have a 37 Tall Gallon reef and am currently using a canister filter. I am not happy with it at all. Even though things are going well. I think they could be much better. So I am trying to DIY a sump. The issue is I have a tall tank and my base it sits on is a vertical base. I have 17 x 19 x 20" tall to work with. So I'm think of cutting the top off a 5gallon water bottle and turning it into a sump. Please take a look at the drawing and let me know if you think it would work of if I would be wasting my time.
