Ok. Did a round of ascorbic acid and waited for stains to lift, added the KemTek HEDP that was recommended, and then added my CuLator 4ppm. So far so good. Everything looks brand new. I forgot to order the Polyquat 60 so decided to just risk it with no chlorine for a little bit. I am now on the 28th hour since introducing the ascorbic acid and about 12 hours since the dose of KemTek. Is it ok to start bringing my chlorine back up now? My pool is blue and clear and I am nervous that adding chlorine may somehow release the metals back into the pool like it did last time. Forgive me if this info is posted somewhere else. I read through a lot of other posts and just didn't see a specific amount of time to wait. Thank you.
