I just set up my 38G AIO yesterday and I'm having trouble balancing the water levels in the back chamber of my AIO. It's a Fuji Cube 38g Peninsula tank.
When the pump is off all of the back chambers have the same water level. As soon as I turn the pump on the water almost completely drains from the return chamber and pumps into the tank. After a few hours of running like this the water level stays near the bottom of the return chamber and the water cascades down creating a lot of noise. I've played with the pump to slow down the return as much as possible, but it doesn't really affect the water level in the chamber. I replaced the pump with a quieter and lower flow pump and got the same results. I could add more water, but I'm afraid that I'll just overflow the tank.
Am I missing something?
