After two years of planning and building my system I have run into an issue with the return pump.
40 breeder with coast to coast overflow feeding to an external box with 1" bean animal drains going straight down through the top of the stand into the sump.
Return line is a short run of 1" hose to 1" pvc running about 4ft to a single outlet into the tank. There is also a manifold hooked up where the hose meets the rigid plumbing.
I was sold a Jebao DCT6000 from another reefer second hand. He said he was using it on a 40b with no issues. I have the pump turned down to the lowest setting and it still seems way too much.
When I start the pump there is roughly 4" of water above it in the sump. Once the over flowing starts the pump quickly drains the last chamber of the sump. If I leave it sucking some air I get a rush of water out of all 3 bean animal drains and the water fills up the sump quickly. The return pump then repeats this process.
I'm wondering if I don't have enough water in the system? When I shut the pump off the water is about an 1" lower than max in the sump (after holes stop siphons).
If anyone has some insight into why this is happening and how to fix it I really need some help.
