I assume this is the best sub-forum to ask these questions:
I have a lot of 3 inch trichlor tabs. They say they are "90% available stabilized chlorine, 99% Trichlor-S-Triazinetrione" on the label.
I also have high CYA at about 85. Boo....
So, once I get the CYA back down to where it should be (Target 30-40), I was wondering how I can calculate how many 3" tabs it would take to raise the CYA by 1 PPM for a 25,000 gal pool (my size pool in this example).
I would also like to know how much CL2 is in one of those pesky tabs. It would be nice to equate one tab is equal to a certain number of ounces of 8.25% Bleach or certain number of ounces by volume of 68% Cal-hypo, etc.....
I travel on biz occasionally, and I think if I can get my CYA fixed (30-40).....I hope it won't be a big deal to leave a couple of these 3 in tabs in a pool floater while gone for a week. Right?
I say this becuase I noticed that when I closed the pool last year and re-opened it, my CYA went from 50 to 0. So it seems "winter" cleanses the pool of CYA, just like a drain out.
On simialr topic, I wonder what the shelf life of these 3 inch tabs is? Can they be stored in cold weather outside in a pool deck box over winter, or must they be stored in a garage where temps would likely stay about 55 F all winter.
