I have an 80gal AGA with 20 gal sump. All the aquarium water is fed into an ETSS Protein skimmer before dumping into the sump. Th esump has three baffles, LS & LR. The right half of the sump has very little movement at all, but if I look closely, I see very fine bubbles. After investigating thoroughly for air leaks into the return hose, I ruled this out, by bypassing the skimmer and just returning the water to the main tank. There were no bubbles. So the problem remains in the ETSS skimmer, where I can clearly see it dumping tons of fine bubbles into the dump. Recommended flow output through the skimmer is 320gph. Mine is measured at 327gph, but bubbles still remain. The system is two weeks old. Any ideas?
Cheers,
Scott
