Jandy SWCG's "optimal" water conditions: why raise CYA?

[BigTallGuy]

Thanks Evan. I appreciate your reply. I am embarrased, and publically admit you were right about the CYA. I must have read the Pool Info, Not the SWCG info. Please accept my apologies.

In my case a few years ago, the Problem with the CYA was on a Fresh fill. I drained my pool to less than 1 inch of water and refilled. After adding the CYA, and discovered the "high CYA Problem", I had the water tested at three different pool stores (before I ever heard of this Forum) and not one could find anything wrong with my pool chemistry. The unanimous consensus was high CYA as the cause of the eye irritation. I cannot explain how 4 Lbs. of CYA took me to readings in excess of 110 PPM in approximately 11,000 gallons of water, nor can I explain why draining 2/3 of the pool water (the following year) and refilling with fresh water took me to 100 ppm. But that pool and all its water and problems are long gone, so it will remain a mystery.

Yes I am a slow learner, I don't just go out and buy or do everything everyone tells me to until I investigate it. After all when your own children and grandchildren tell you that their eyes burn in your pool, I will err on the the side of caution. As far as the test kit is concerned, my old one was barely adequate, but wouldn't test CYA, so yes, I ordered the Taylor.

Thanks again Evan, and Peace.

Rick.
