I'm doing a fresh water test of my 125 gallon, and am getting microbubbles. I'm running a closed loop with a Barracuda, and a sump with a Mag9.5 pump with the return split to a fuge. If I run the closed loop by itself, no bubbles, but when I run the sump return, I get the bubbles. I figure it a 'real' problem, but just thought I'd ask, is it possible (or even maybe likely?) that when run with salt water the problem will go away? I'd rather get the answer to that than unnecessarily try to solve a non-existant problem. Hoping against hope, I guess.:D Any ideas would be greatly appreciated!
