I just built my wet and dry for my 75 gallon African tank. It incorporates a sterilite 3 bay container, a sterilite refugium. a diy algae scrubber and a sterilite pump container. The 3 bay container has filter media in the top drawer, and bio-balls/scrubbies in the second drawer. I haven't put anything in the bottom yet. I took a container for the fuge, and drilled a ton of holes in it, put some gravel in the bottom, and am growing anacharis in it. I was thinking about putting a couple skunk loaches in there to eat any snails, but i'm not sure yet. The pump container is set up so there is zero chance I can flood my tank if a overflow loses siphon. I didn't really like any of the pvc overflow designs I saw online, so I came up with what you see. I also used a gas can squeeze type vacuum pump, and rigged it so I don't ever have to siphon with my mouth to start the system up. I also have a Fluval 405 in case the sump fails. So far so good. The tank is a 75, and the sump is a 75. Let me know what you guys think.
