I’ve been struggling to add a sump to my tank because my tank is built into the wall and the largest sump I can fit below is about 40 gallons, which is too small for my tank. Even at that size, it’s super tight and a pain to work with. I’m considering putting some sort of bulkheads through the exterior wall of my home and putting the sump outside. I was thinking I could build some sort of insulated shed for it. I live in California and so freezing isn’t really an issue, but maybe heat could be in the summers. Has anyone tried this? Anything I should be aware of before I go about implanting this idea?
