Aquarium Advice FINatic
I'm going to be making a 20 gallon sump for my 56 gallon tank. What I don't understand is when there is a power outage, is there a way to keep water from my tank from being siphoned into the sump automatically? I will not be drilling my tank as its been established now for two years. Trying to evaluate all my options before I start the build.
