Function
The 137i Impeller is the only moving part in an Aqua One Ocellaris 850 and 850UV are completely dependent on the impeller to produce water flow. If the 137i is dirty or worn flow rates can be reduced to a trickle and the filter can easily become noisy.
Lifespan
Experience tells us that most impellers give of their best during the first year of their life. The 137i impeller will turn through billions of revolutions during that times so changing it yearly or at least having a spare is common sense. its perhpas best not to wait until it fails and leaves you filterless.
