If it was my pool and I had sparkling water, I probably wouldn't worry about CH of 400. That's not super high. In fact, the suggested level is 200-400. But, I would not use any cal-hypo and I would not let my TA and pH get high. Just my opinion.

(Note to others reading --- vinyl pools do not need calcium 200-400.)

Thanks.

I had come to the same conclusion- that 400 was not too high to worry about. My CYA is 75 & I'm using about 182 oz. of bleach a day, sometimes a bit more (364 oz.). I have been thinking of raising the CYA a bit higher (85-90) to hopefully use less bleach as you had suggested a while back, since my pool gets full sun all day.

What do you think?

If you are using that much bleach each day, you probably would do better with your CYA a little higher. Take it up slowly, though. Don't want to overshoot your target.

You're only a couple of hours away from me, so my climate is much the same as yours--you'll find that you lose a LOT less chlorine if you'll bump your CYA up to 90 or so! That's where I keep mine--and my chlorine loss is only about2-3 ppm daily.
