I am having trouble with my new closed loops. I have one on either side of my 125 gal. reef tank. Left side uses a mag 12, right uses mag 18. Problem is, both pumps makes alot of noise. I ran the pumps alone in a bucket and were completely silent. But unless I close off my valves almost all the way, they are way loud! I increased the inlet piping to 1" thinking the inlet was restricted, but no change in noise level at all. The left side(mag 12)supplies a 3/4" bulkhead, and a 1/2" spraybar at the back of my tank. Problem with that is, I only get flow through the bulkhead, not the spraybars. I blocked off the bulkhead and get VERY LITTLE flow through the bars. I used a T to supply the output to the bulkhead and spraybars. Right after the tee I reduced the line to 1/2" flexible tubing. Goes up to the top of tank, the down the back wall. Think I should increase the line to 3/4" all the way up my tank, only reducing to 1/2" when it reached spraybars themselves. Look at my rough sketches, see what you all think. Please help!!!!!
