About to start building a frame to hold the frag tank and refugium. This is what I came up for positioning of the tanks.



My question concerns the plumbing. Rather than running a seperate line to the frag tank and refugium if I plumb it as I've drawn then I think it should work with one line. The way the water is diverted, I can have more flow in the frag tank and less in the refugium.

Since water entering the frag tank will be equal to the water exiting the bypass, I don't need to increase the size of the pipe after the bypass reenters the ouput line (circled area of plumbing) - do I?


No - the frag tank isn't hitting the ceiling. One square equals one inch. The top of the frag tank is at about the 5 foot level.
