Sometimes (lets say once a day) my Penguin Mini makes a churning sound, as if its filling itself with water, for a few seconds. As it is stopping, tiny bubbles are comming out of the filter out-take. Then it stops and continues running quietly.
I'm not quite sure why its doing this, but I am wondering if it is time to consider looking for a new filter to have as a backup (if I can find a sale on one now it might be better than having to run out to the store and pay to much).
You thoughts?
