Shelf life of Trichlor Tablets

[mrsfish]

I am a new pool owner (4 months now) and have recently due to chlorine lock from high CYA switched to BBB method. I am stocking up and researching buying bleach, but am wondering what to do with the 40 or so remaining trichlor tablets I have. I am assuming at some point my CYA, currently 60 after draining, will go down and I could use the tablets, but I don't know how long that will be and if by then the tablets will still be a good source of chlorine...

Thanks!

If you keep them dry and sealed in the tub they came in they will last a very long time.

You can use them once you get your CYA down to a reasonable level. For example, if you have to go out of town and need something to hold CYA up. I don't recognize your filter, but the occasional use if you have a DE or Sand filter is not too bad, since you'll be washing water out each time you backflush.

Make sure the lid is on tight and I'd guess they'll last years.

Yea seal them up and they'll be good for years.

I switched to bleach about 3 years ago and had about ½ a bucket left. I only used it for vacations and to bring up my CYA each spring (it seems to zero each winter). Just used up my last puck this spring. It'll keep as long as it's kept dry.
