my husband, also my pool man, was recently deployed to afghanistan. he has always used TFP and the BBB method. i now in charge of the pool trusted our local pool chain to guide me (i was unfamiliar and afraid to use TFP). i have been battleing our pool for over a month now and am seriously looking into the price of concrete! i have also done everthing the pool store people have told me to do, spending $100.'s of dollars. long story short, in attempts to shock my pool twice, the metals in the water were activated turning the water a rusty color. the first time successfully cleared and no stains remained with the suggested product metal free. this time no results after 2 bottles of metal free .in addition to the 3 bottles of metal free, I have added a 50lb bucket of soda ash, probably 12-15 gal of 8.25% clorox, an algaecide "that will kill all algae in the pool, even black algae",(even though there was no black algae I could see) as instructed by the pool store pro's. i actually drained the pool about 4-6 inches and refilled with new water. we have city water, no heater, and no leaves allowed to remain in the pool. the stain will fade with rubbing lemon on it. I have a TF 100 test kit, filtering 24/7, brushing multiple times a day, the water is light green in color, and the liner and steps remain stained. These are my current chemistry readings, can you help?
