Hi all today i notice one my powerhead impeller wasn't turning so i disassemble the unit a clean around the magnet and man the smell and the dirt that build up of food and other stuff.I like to now how offer you clean your powerhead
every 2 months I let the power heads run in a gallon of vinegar for about an hour then I let them run in clean water for about 2 hours, I change the water after the first half hour, then at the hour mark then the 1 1/2 hour mark Then I put them back in the tank.
