I have just installed a salt system to my pool.. I got a pool guy that got all the levels perfect the water was blue and perfectly clear.. then all of a sudden after a rain the deep end starting getting a yellow tint to it.. I called the pool guy.. he says probably pollen then he gets there and says he wasnt really sure what it was. He then proceeds to shock it. I left came back an hour later and the water was completely green.. but it is still really clear. just tinted green.. I have the circu pool rj45 chlorine generator. After reading some post i assumed possible metals in pool.. I took a sample of water to Leslies pool store and they said i had 0.5 of iron in pool so I bought metal free. I added it and still is green.. but very clear.Should I continue to run the salt system while this is circulating?Does this sound like a metal problem?
