Yes, I can remove the bio wheel, however not sure at the moment what can be
done to plug up the spray bar that turns the bio wheel. Have to give a look
tomorrow while doing my cleaning.

Not sure what kind of filter you have, but in many of them, if you remove the
bio-wheel, it works pretty much like an Aquaclear. The water just "waterfalls"
back into the tank. There is less turbulence, because you don't have the
bio-wheel spinning and splashing. And if you keep the water level high, the
water falling back into the tank doesn't cause too much agitation.
