Stabilizer

Yes use the pucks so Trichloro-s-triazinetrione in the ingredient in there and my shock is sodium dichloro-triazinetrione dihydrate. My CYA is high the pool store said 100

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.

Sorry CYA is 100. The pool has always been clear even when we open it.

CYA of 100 is still pretty high....I suggest that you immediately stop using the dichlor shock and trichlor pucks, and switch to cal-hypo or bleach to chlorinate and shock with. Otherwise your CYA is going to continue to rise to the point where it's impossible to keep your water clear.

cal-hypo is just another brand of shock?

Thanks

Cal-hypo is another form of chlorine. "Shock" is actually a verb, something you do to your pool, instead of a noun, a thing. To "shock" only means to raise your chlorine level to a high level, no matter which form of chlorine you use to accomplish this. Some pre-packaged "shocks" contain cal-hypo or calcium hypochlorite, and are a much better chlorine alternative in your situation because it does not add CYA to the water like dichlor does.
