    Clear Green Water

    I, on the other hand, need an idea about my clear GREEN water. It happens after filling and usually goes away in 24 hours, but this time, for some reason, is ongoing several days with no end in site. Any idea about this? ..it almost looks ok, except light, clear green.

    New Mexico, 18000k concrete in ground, 65 degrees, FC 3-5, TA 90, pH 7.3, CYA 30, Borate 40--everything chemically looks good.....

    It could be copper or iron; if you have a bluish pool finish, yellow-orange from iron can look green.

    You could have your fill water tested for metals.

    Went to the pool guy and got a quart of Bioguard Remedy metal magnet, 18 bucks. It is diphosphonic acid-based. Put it in, started circulating, and the water was blue and clear as could be in two hours. Just wish there was a cheaper substitute, alas, pool guy wins again.

    I've had great luck with HTH Metal Control from Walmart. It's around $10 per quart, its phosphonic acid based, and half the price.
