Bubbles

[MRDHJ1]

Heres the question? In the last two weeks I have started to get little bubbles on some of my rocks. Nothing has changed as far as the system goes. except the top off but that is in the sump. what do I need to do

i had that at one time. it just went away on its own

Make sure you have enough water movement.
but i wouldn't worry about it too much.
