I have a 180G tank and have recently purchased a Jebao DCT 18,000 return pump. The fitting for the pump is 1-1/2". My current return plumbing is 1".
I am planning on building a manifold to run my UV sterilizer, algae scrubber, and carbon reactor. My problem is that when I shut off the tank my sump fills with water to a level that I am not comfortable exceeding.
My return line T's into the display tank at the top and I have a hole on the right side drilled at the top of the water line. If I up-size to 1-1/2" there should be more water draining into the tank right? How do I keep this from happening without adding a check valve?
