I live in sunny hot Phoenix and this is my first year with a pool, it was finished in May. I use Trichlor to chlorinate it and when I did my first CYA test a couple of months ago it was over 100. I diluted the water for over 24 hours (filling and draining at the same time) bringing it to 50. I recall also then lifting CH at that time to 250. Today (2 months later after the hotest part of the Phoenix summer) the pool hit CYA of about 170 and CH at 375. Wow, had to dilute again this time for about 36 hours. And I am going to start using Bleach now to chlorinate, something I tried doing 2 months ago but thought it was not worth it. I was wrong.
I am hoping to ask here, to someone who knows chemistry, why they cannot make a tablet that does not contain tons of CYA? The alternative seem to be ones that contain calcium but adding cacium in Phoenix wher where the water is hard and there is much evaporation is not much better. Or lithium which is very expensive and not readily available. Clearly there would be a huge market for a tablet that did not add anything to your pool but sodium hypochlorite. And further, why even add CYA to Trichlor? You can put in your own CYA in the pool just once and leave it. To someone with as little knowledge of this as me, Trichlor minus CYA equals a huge selling product.
I am aware there are simple answers to these questions... Just want to know what those are. Thanks!
