Power head/water pump maintenance.

An essential thing to do is make sure the power head or water pump that is the return pump from the sump is of the best possible quality, if this one breaks down you will most likely loose your aquarium life forms if it is not functioning and not noticed for more than 6 hours.

Any and all power heads and water pumps of all types should be cleaned each month or at the most each two months, circulating pumps in the tank need to be cleaned with vinegar or light acid to dissolve any calcium build up and than use a scourer and brush.

If regular cleaning is not carried out on power heads they may seize and fail, causing permanent damage.

This is very important if waters before pumps are not pre filtered to at least 100 microns!!

Power board burns from water getting under the plug, spray them with silicon lubricant and lightly wipe this off before use and keep them dry.


Cleaning impellor should be done with a brush or some scourer and sponge gently as to not bend the shaft for the impellor.

With wood or plastic only, tooth pics maybe or a piece of plastic, no metal should touch any of the pump areas unless you are very gentle with it.
Be gentle with the shaft the impellor slides down onto. See the yellow part, that part incorporates the shaft, so if the shaft breaks or is worn, that part is replaceable.


These brushes from a junky shop are great for cleaning in side the impellor area.

Where this tooth pic is laying is where water will sometimes lay and the electicity will arc across between positive and nagetive terminals causing a carbon build up and this will continue the arcing until cleaned out of the burnt groove,once this happens its best to get rid of the power board totaly.


These pics show the rubber caps that act as a bearing in many cases, these should replaced if worn. The pics are of both porcelain and stainless shafts.
