Cleaning Air Stone Diffuser
How often do I need to clean out my air stone diffuser?
Your air stone diffuser will give you the best performance if you clean it every year or two.
If you raise it up and it looks clean, then just lower it back down. If it has mud, algae or other things clogging the pores, then it should be cleaned. You can use a 10% solution of muriatic acid or give it a gentle cleaning with a steel brush. Putting it into a clean bucket of water and blowing air through it after cleaning is a good way to make sure the pores are open and that it’s operating correctly.
If you have a rubber membrane diffuser, it may not need to be cleaned. You can check it by blowing air through it to check its performance.
