Try to follow me on this one. I just finished constructing my prop tank that will soon be going under my main I have discussed several methods of moving water through it and came up with this as the best idea (since pumping water in both directions is out of the question) I constructed a basic u tube of pvc that will hang on the back of my overflow on my main. (pictures below) My main overflow leads down into a sump with live rock rubble im thinking of putting this in the back compartment of the overflow having it syphon water down into the prop tank and moving water back out of the prop tank via pump back into the return compantment of my sump this would all be controlled by ball valves to make sure the water coming into the tank is equal to the water being taken out the question is with this pvc u tube i made whats the easiest wat to start the syphon down into the prop tank?
