Aquarium Advice Addict
I have a Marineland® Penguin® Bio-Wheel Aquarium Power Filter 200 on my 29 gallon. The bio-wheel doesn't spin as free as I think it should. I've mined my top away from it a bit thinking that it was inhibiting the movement, but I don't think it helped. It has the front cover, should I take that off? The wheel is in the correct slots. Please help thanks.
