You have any ideas on that one? I also think that the failsave is more important for you since you have live fish. Plants are more forgiving if they don't receive the right treatment.
i personally have not had the issue but with our float switches being directly in contact with water and chemicals you will likely have to deal with nutrient build up and myself having hard water issues and algea.
Others report that the switches get stuck so i guess clean them often. In my situation i cant have very much overfilling without having issues a possible idea is to take two pieces of wire seperated by small distance program them like a switch and mount them on the side of my tank if water overflows it should short and then turn off all pumps or whatever action.
I previously had some large tomato plants growing hydroponically but i didnt understand the manual pollination process do i had tons of flowers but no tomatoes. amatuer move
