Blue Small
Monday, July 26th, 2010does anybody know how to effectivly clean the small blue airstones?
I am trying to find a way to clean the blue airstones that are made by blue mist for use in undergravel filters. I have tried muriatic acid and vinager, but the acid destroyed the airstones and the vinager did nothing. Any suggestions would be helpfull.
Usually buy a new one, or use a toothbrush.
