bubbles under rocks

[AquaAdam]

Hi everyone, Are bubbles under rocks a good thing or a bad thing? I'm assuming its happening from the way the water is flowing in the tank.

Are there micro bubbles coming from your sump?

Do you mean any bubbles in the sump itself? Where the line goes into the sump, yes bubbles rise to the surface. At the return end I will have to check.

is it bad to have bubbles in your sump?
