I just built a new sump for my 90 gal
RR. The sump will hold about 25 gal
at full capacity. From the tank I ran 1 1/4" clear tubing with a ball valve to control flow. The water feeds into an area about 3" with a 1 foot baffle. It then flows over the baffle into a larger area of about 1 cubic foot of space. It then flows under 1 bubble baffle ( about 6 inches from the bottom), over one baffle and then under the last baffle (again about inches from the bottom) into the area where I have a Quiet One 6000. The return line is 1" clear tubing with a ball valve in the line.
I cant seem to get the bubbles to stop going into the tank. I have tried to "tune" the system to allow the input(from the tank) to equal the output (the return to the tank) of the pump. Everything works great until the water in the sump equalizes(becomes level across the entire sump). That is when the bubbles start rolling down the input tube.
I know this is long and somewhat complicated to visualize and I have read as much as I know how to solve this problem on my own, but I need your help. Any suggestions would be appreciated.
