Trying to.raise cya. It's about 10-20ppm currently. I have 3" pool line slow tabs and contain 99% trichloro-s-triazinetrione. Does this.have stabilizer properties? And can it be used.as conditioner. Thanks in advance.

Yes it can be used to raise CYA -- think of it as chlorine and CYA combined, but in the water they are measured separately. This is Trichlor where for every 10 ppm FC that you add it also increases CYA by 6 ppm. That will be a slow rise, but if you are using 2 ppm FC per day, then you'll increase CYA by around 8.5 ppm per week.
