jblizzle said:Depends what is in the water. If the water were clean, then you would reach the target FC in 30 minutes. But if there is something in the water then the FC would be consumed.

jblizzle said:Well the CYA had to come from somewhere. Did you use any solid form of chlorine? What kind of lighting were you in for the CYA test?
Have you performed the OCLT?
nismostate said:Are you sure the 30,375 Gal is correct? I had to play with the pool size until the chemicals added = chemicals measured according to pool calculator.
jblizzle said:6 pounds should have only raised your CYA by 24ppm ... so I have no idea how you are now at 60ppm, unless you did not start with 0ppm.
What does the water look like now?
Sounds like the pool is likely between 27k and 31k ... kind of depends on the depth profile.
jblizzle said:No the metal will not affect the CYA ... although it could be causing the water color if it is clear.
You have nailed it! Pristine Blue adds Copper.Okiesummer said:Ok! After some studying in Pool School, I think my water color issue is from the copper in the water. The water that I get for my testing is clear but the pool looks light green. I would post pics but I can't catch the right light to show the true color. I checked it and I am at 1.0 ppm of copper. Does this sound right to anybody? Could that be why I'm not seeing a drastic change in the water color? Or have I not been shocking long enough?
With my CC still at 1 should I maintain shock levels until the CC gets closer to zero before trying the OCLT?
Also, do I need to wait until after the shock process to add some sequestrant?
