Yes, I am testing in fresh water, prior to modifying my sump. I am letting
it run for the breakin period and it has about 2 hour of continous
operation.

are you testing it in fresh water ???

Just purchased a new Kent Nautilus TE in sump skimmer and am using the
Rio
2100 pump Kent recommends. I can not get the unit to generate real fine
bubbles. The bubbles in the skimmer are approximately 1/4" in diameter,
thus it is ineffective.

those seem large but a break in period is required

Does anyone have that skimmer which works well or one with a similar
problem. Have a message into Kent but no response. Would like to get
working right this weekend.
