im getting fed up with the impeller of my L30 with the nylon ring falling off the magnet. i did give hydor UK a email, they might be sending one over, but just wondering, does the impeller NEED the nylon ring there to work? or can i just take it off once and for all? heres a picture:

ive tried to super glue it many times, but after about 3 weeks it would just fall off again.
