Hi- I have had this penguin 150 going for about 2 months now, but have noticed that the wheel moves like a few times every hour, and that is not a complete spin, but rather a few notches on it. The flow rate is strong and the intake tube has no blockage. I know you can call Marineland's hotline, but I am just curious what fellow penguin users recommend. The bio wheel never needs replacing, but it makes me wonder at times as it the reason why it does not move is due to the bacteria and water buildup. Anyway, as always, I would appreciate any input.
