I’ve noticed recently that a Hagen BioLife 55, I’m using on my L190 & L001 aquarium in the fish house, has been pulse-ing on and off. I though it was a worn impellar, so I put it on my “todo” list to purchase a new one next year, it started to get worse, so I checked it over and it looked okay, and seem to work okay when removed from the filter body.
Ah, found the problem, if the filter media gets clogged, it stops the flow of water and the impellar stops! TIPCheck the Hagen BioLife filter media regularly. I will do from now on.
