Both of those contain stabilizer, so you have been adding it, even though you didn't realize it. Your stabilizer reading is way, way too high. I'm surprised that you haven't started having problems keeping your water clear--and if you haven't had problems yet you will very shortly. I highly recommend that you drain part of your water and refill it to lower that CYA level.
