I'm glad you are having some success! I would keep the filter running, and keep your chlorine at 5 (it is not shocking your water at that level). If you can give us a new set of numbers it would be good. The metal out you put in the water probably took your ph down. I would not add anything else for now. Just keep vacuuming and see how it looks tomorrow. I would go to regular bleach. You don't want to add anything but chlorine to your water. Your cya is already at 60, and you may already have a high calcium level. You just have to keep the chlorine up there. You don't have to shock for now if the pool is holding chlorine.
