Is it enough to freak out about? I personally don't like to see anything above 0.0. It seems to be spread out from about 4 or 5 different items each leaking about .2-.3. :?
I'm going to see what I can do about it, obviously, but if it comes down to replacing the sump return pump or my skimmer pump then that's a fair chunk of $$$ cash.
What really bugs me is one of them is an air pump, and save for the silicone air tubing running into my sump, there's no connection between the pump itself and the water ..... but it's pretty consistent beween "pump unplugged" and "pump plugged in." Unless there's something goofy with my ground itself.
