BODYDUB;4234097; said:Yes you do, or you can just go to walmart and buy a aquatech 30-60 filter that has a seperate filter that you never replace for BB. It's around $35. IMO I would just buy another filter. That filter you have looks like a Emperor and it's missing a bio-wheel. Alot of people have problems with the bio-wheel stopping from spinning........
I had a biowheel that stopped spinning and I just washed the areas where it spins(and the two purple things that hold it up), and now it spins faster than the other biowheels
