Mine didn't stink...I think it was the microalgae, not cyano.
I'm going to do my normal 20% PWC today/tomorrow (sick daughter today, so we'll see how much time I have), and will retest everything with my new Hanna and Salifert kits (PO4, NitrAte and Magnesium). I'm 99.999999999% sure everything is in check, so hopefully once I've gotten rid of it, it will stay gone.
I've gone back to the IO Reef Crystals for the time being. I'm keeping the RSCP bucket, and will roll it before I use it again. I don't think it was the salt, and I'm not going to waste the $$ on the bucket and toss it.
