Have added 400 oz bleach last night and still no FC in pool or no CYA. Added 4lbs cya last wed but still not testing or i gess i shoukd say the level is actually 9. Can I continue bbb method and added another 400 oz bleach or do I need to add a powdered dichlor with cya bought from biogard called smart shock? It has copper in it which scares me and I would rather stick with bbb method but how do you raise cya on bbb method?
