did anyone try using the metal out first? before adding the chlorine. I just spoke to a lady i work with and she said she ran into that w/ her pool the first year. she added the metal out stuff. let the pool sit w/o filtering. then vacuumed the bottom. she said as long as she used that she didn't have a prob. She said that she also has a hot tub and now uses that before she adds chlorine and doesn't have a problem. I just want to know if her story is just a fluke or if anyone tried this metal out stuff 1st before anything?
