memorywrangler Posted May 6, 2022 Share Posted May 6, 2022 I'm trying to build the smallest overflow possible. I have a 5-gallon shrimp tank with some very tannic drift wood in it which water tea-colored in a week. I don't like the way it looks but: I don't want to tear it down to replace the wood Every time I do a big water change, some shrimp die. So I'm going to build the tiniest overflow possible and add a pint or two of fresh water every day. Since the tank is so small, it doesn't make much water to raise level 1/4 in or so, which should be enough to run the overflow. Hopefully, this will keep the shrimp happy and my water clear(er). Here was my first attempt built from rigid airline tubing: But it was too narrow -- the surface tension on the water was strong enough to hold back the flow. Here's the second try: it's made of 1/4 acrylic tubing with a small hole drilled at the top of the loop to break the siphon. The tube runs to 5-gal bucket under my desk. It's working fine, but it could be tidier. 2 Link to comment Share on other sites More sharing options...
