Hello, here goes...
I currently have a very simple setup where the tank drains to the
sump and a return pump pumps water back up. I have set it up so if a power failure occurs...there is enough space in the
sump to accept the extra water that will drain.
Now...i'm setting up a separate refuge. So if you can picture this..the drain from the tank will be split and some water will flow into a different smaller tank and that tank will have a small pump pumping water back to the tank...how do i design this so its flood proof as i did with my current setup?
hope this is making sense.
thanks
