Grace, all I did was take the mineral/chlorine cylinders totally out of the cycler and started doing the BBB. You could really tell the difference pretty quickly after adding the bleach. The cloudiness went away and the next day I just vacuumed the dead white algae off of the bottom. (at least I think it was dead white algae !?!) The water is now crystal clear, so maybe there wasn't enough "minerals" to pose any kind of problem.
