After doing some reading it seems as if I have iron or copper in my well water. It turned green with in a minute of shocking it. Pull some out in a clear glass and it is crystal clear. I tried HTH metal control and it has not seemed to do anything. I stopped and picked up a 4ppm CuLator and now 5 hours later and the water is nice and clear. From reading here I see that I am in need of a good test kit and I will order one soon. All I have right now is a 3 way tester and my chlorine is now down to 1 and ph at 6.8. From what I have read it seems those are perfect levels for the CuLator to work best. Anybody have any thoughts on the CuLator and my situation in general? I got the HTH Chlorine tabs but if I am understanding the stuff I am reading right they are not the best thing to use because they slowly raise some other level that starts to make the chlorine not as effective? I have the 15'X48" version and it holds about 4400 gallons.

Any help would be greatly appreciated.
