18 tall DIY sump
We're going to go w/ a sump for our 40gal long tank. We bought a 18 tall as a DIY sump. I'm enclosing a picture of how I'm thinking of sectioning off the tank/sump. I'd appreciate anyone's input of this might be a good idea or if anyene has a better idea/way of sectioning off the tank/sump.
Thanks in advance!
