5. Test air pumps: Air pumps should be tested and if not working buy a new one or buy a repair kit for half the price of the pump. For aquarium with power filter, remove impeller for cleaning. Clean the slime and gunk off impeller magnets to improve the efficiency of the unit. If the impeller magnet is very dirty then soak in vinegar or lemon juice. Use same technique for cleaning power heads for filter units.
