No. I wish you hadn't added that stabilizer yet. Actually, we usually advise people to forget about the stabilizer while they are fighting algae. While you are trying to clear your water, you are most likely going to be vacuuming and probably backwashing often. (Backwash whenever the filter pressure goes up by 8-10 psi over your clean filter pressure.) Stabliizer (cya) dissolves really slowly in your filter -- maybe even up to a week. So, if you backwash in that week, you end up throwing out the stabilizer.
