Hi Watermom,

I have definitely shocked the pool - I added ~ 4 qts of bleach last night and now my chlorine levels are above 15 (I diluted my pool water with 1 part pool water, 2 parts distilled water and it measures at least 5, maybe a little darker. Multiplying by 3 gives > 15). I also noticed that pH sky-rocketed as well. It is now > 8.2 (previously was steady at 7.5). Does the excessive bleach/chlorine of the chock treatment also increase pH levels?

One additional fact I forgot about is that I added 12oz of hth "metal control" after filling my pool with water (before adding any other chemicals). I had read online that this should be the first step in the water treatment process. Could this be the cause/source of the light greenish tint to my water?

After further review of my pool & water, I realize the the light greenish tint is in the water, not on the liner. NOTE: It is still present after the shock treatment. If I change the angle at which I look through the water, the "blue/green line" I see along the side of my pool "changes its location." It must have something to do with the pool water chemistry that is causing the light greenish tint to my water (still very clear). Could it be caused by the "metal control" that I added??? If so, is there a way to reverse the effect, i.e. drain some water and add new water? If so, how much should be drained? Or is this something I just need to accept for this season?

I look forward to your response. Hopefully my Taylor kit arrives soon so that I can get more accurate measurements.

One last question/concern - do I need to be proactive to reduce my elevated pH level? Should I take action to lower it or will it lower on its own as the chlorine level drops?

Thank you in advance for all of your support.
