My water has a green tint to it. It is perfectly clear and tests good. Shows no metals and everything reads good. what could this be? Been going on for two weeks now. What can i try to clear it up?

Possibly chloramines. I just saw this:
"Chloramine-treated water has a greenish cast, the source of the color is uncertain."
http://en.wikipedia.org/wiki/Chloramine
I had not heard of chloramines creating a greenish hue, but I suppose it's possible.

Just got a new pool and there was not enough free cholorine. Had the solar cover on w/ pump running. Put in two bags of shock and it turned a clear yellowish/green color. I do believe that it is CHLORAMINE.

Thanks for the info.

My water has a green tint to it. It is perfectly clear and tests good
If it is perfectly clear with a green tint, it is usually an indicator of metals (iron) precipitating out. The solution is lowering your pH, keeping it lowered, and probably the addition of a sequestrant to keep the metal in suspension.

A full set of test results including pH, total alkalintity, Free chlorine, CYA, and Calcium Hardness will be very helpful in analyzing the issue.

When was the test for metals completed? I would consider getting another test from a different source.

As mentioned above, it might or might not be chloramine. Please do a test of all the constituents and their proportion and you will know what exactly is causing the problem to your swimming pool water.

My problem exactly whereupon we consulted my Friendly Local Bills Pool and Spa who sold us a 16-lb jar of granulated Na tricolor, advising me to just to just toss it in, whereupon my 35kgal turned gorgeous blue though setting us back $70

So now, the problem in your water colour gets solved :-) Do you have a maintenance contract with them?

my pool is clear but has a green tint how do I fix that? Its an above ground pool. Is it the sand in it that is causing this?

If the color tends to fade if you lower the pH, then it's very likely to be metals in the water. Use an HEDP-type metal sequestrant as described in Metals in the Water and Metal Stains .

sounds like you have a phosphate problem.
