Could I just remove the wheels without throwing off my bio cycle?

Sometimes the biowheels can get dirty, and swishing them around in aquarium water every three or four months might help. Not a good idea to remove them for they also hold a great deal of beneficial bacteria.Might also need to clean the filter material a little more often or replace it. Always clean in old aquarium water that you take out during weekly 25 to 30 percent water changes.
Wouldn't worry about bubbles as they are providing oxygen for the fishes.
