I seem to be loosing CYA a lot more quickly than salt. For this year I have added no salt and it has dropped from about 3500 to 3000 since January. In the same time frame I have had to add 90 ppm of CYA to keep my 60-70 level.

Is there anything other than splashout, backwash and heavy rain overflow that can cause CYA to drop?

I've had the same issue, CYA just vanishes, and does so faster than the salt. My pool is fine otherwise, always clear.
