My CYA level on 6-16-13 was 50. I have nothing more to test CYA levels with until my kit arrives. With my chlorine "dilution" testing being at 4-8 (that's using an hth drop kit with results of 2-4 multiplying x2), I don't know how to lower the chlorine level to match the CYA. I'm reading all over your site but there is sooo much information! Sorry I can't find it.
