I have an Emperor 400 which has 2 bio wheels and I was wondering if they r good or bad . I have been reading that bio wheels and other bio filters may produce substantial amounts of nitrate. I have always had a problem with nitrate even after I cut down to once a day feeding with little amounts.
Just wondering how u guys feel about them. Should I remove them or not?
Your assistance is greatly appreciated and Thanx in advance
