Hello every one,
I recently upgraded my tank from a 55 to a 65 with a 20 gallon sump. I added new sand. And after i had it all setup i found air bubbles in the sand. so i mixed the sand around pretty good and i think i got most of the bubbles out. if there are still a few left, do you think that could become a problem? and can i find a creature for the tank that will mix the sand around?
-Thank you
