I just put sand in my tank and i had an airston in there to but it just blows the sand around. it was not buried or anything either. Is there any way i can have an airstone or something in the tank to aerate it without having the sand go everywhere?
Be creative man.....put it under some rocks....behind some wood...or like others have said, turn the bubbles down! I have sand and two bubble discs buried. If I have them on full blast they will come uncovered....so I just turn them down a bit with the valves!
