Air Bubbles Bad?

[bheron]

Sometimes the water level in my Wet/Dry reservoir gets so low that it sucks in air and shoots little air bubbles into my tank. I know this isn’t good. How bad is this and what kind of long-term problems can this cause?

There would be no problem, just fill her up whenever you see it happening. Bubbles come out of mine pretty frequently because of evaporation, just put more water in and they will go away.

It happens to almost everybody that has a sump, imcludeing me. I would just add a 2 gallon bucket when evaporation happens and add kawlkwasser(wrong spelling i know..) and just let it run out slowly.
