How To: Clean a Juwel Power Head

This can be applied to cleaning any aquarium power head, although this guide shows the specifics for cleaning the Juwel Pump or Power Head found in the Bioflow filtration systems.

This will happen to most of us, and i have definitely seen the question pop up on various internet forums.

"My power head has failed, and will not start!”

This is normally exclaimed when the power has been turned off so the filter can be worked on and then the power head fails to start when switched back on.

There is no need to panic or rush out and buy a new one. For one the Juwel power heads are very reliable and rarely break down, it is more likely that it is full of muck, jamming the impeller.

I have a schedule to clean my own at intervals, but sometimes it does get dirty before hand and then presents the typical start up failure.

Here is a quick 15minute process to get it up and running again.

Start by completely removing the power head from the aquarium and take it to the kitchen sink…

Separate the pump unit from the holder. You have to slightly splay the two tags with the holes in, then wiggle the black pump up and out of the grey holder. Don't bend the tags too much, or they will snap, only a few mm on each side. The pump may also be in there quite tight, just get a good grip and wobble it, it should eventually free itself and slide out.

Plenty of gunk in and around the vent and the impeller itself…

Now for the impeller, handle it with care and don't be over zealous near the blades as they are only made of plastic, either use a cloth or the brush to clean it up as it’s the film of muck around the magnet that was most likely binding it up…

Run the power head for 5 minutes, back in the sink “just in case!”

Replace the power head in your aquarium and it will fire up first time at full “as new” performance levels!

Clean your filtration power heads and pumps every 3 months, and circulation ones every 6 months to keep them in top condition and performing the best they can.
