ok i rechecked the cya to make sure my reading was true. I did it before you told me to do it in sun so If it every gets sunny here today I will check again. I got a 50 again and that should be accurate reading due to cya mixed for a week now. I was shooting for 60 but backed off so that I wouldnt over shoot it. I am going on vacation for a week and will be using 2 3in pucks in floater so that should bump my cya some. I wont move it more till I get back and see where Im at.
