Can anybody tell me if there are trichlor pucks made without stabilizer. I found a half filled 25# bucket in my storage shed and it has 90% available cl on the ingredient list with no stabilizer listed. I would like to use these up,but don't want to add cya,or would small this small amount of pucks add that much. My cya is now between 40 & 50,cl 6,ph 7.6,ta 80. THANKS
