Hi all,
I am currently setting up a new 45-gallon tank. I have two issues that I need help with.
The setup is, tank with an overflow box on the side, piped down to the sump, in the first section I have the pipe coming down from overflow into filter sock, with the pipe sitting above the water level. Then there is a baffle, followed by a section for refugium followed by another baffle, then the last section has a return section with a pump in it that push water back to the tank above.
The first issue I have is bubbles coming into the tank from the return pipe, but I think this is my return pump is too small and the pipe has bends which are leading to air in the pipe, any suggestion on other reason would be great.
The second and main issue is the overflow box stops working. I set the flow working in the tank and sump, seems to going well and staying level, but at some point, the overflow box seems to stop and then the pump in the return keeps going till it pumps all the water back into the tank which then overflows and goes on to the floor. At one point I thought this was because my overflow box pipe was going into the water in the sump and not above it, so I changed that, now a few days later I find it happens again. The only thing I can think is that the pump in the return section stops and the overflow box stops getting water, and then the pump starts again, but can't understand why that would happen.
The overflow box is a Skimz OM2500.
I have attached a completely out of scale drawing of what I have, might help.
