Hydor Air Pump

I added one of the above, hidden by plants and today the blooming thing isn’t working, had to rush off to work this morn so I didn’t get a chance to have a fiddle, but has anyone ever had a problem with these? Could the sand of got into it?

Constantly happening to me. Take it apart and take out the impeller then put back together. Usually works

use two of these, no problems for past couple of years. Make sure the sponge is in place, air intake above water line, or as prev posts says, take apart.
