A long time ago, I came here for help on a nitrate problem. you helped me solve it by doing a bunch of things. One of them was to remove the bio wheels from my emporer filter. I did remove one, but was nervous to do both at the same time. So, I have one in there since I did this. Which by the way was easily 8-12 months ago. I have not had a nitrate issue since. Can I get rid of the one bio wheel, of completly remove that whole filter setup??
