1 year old pucks still OK to use?

[CandyMoss]

yeah - my PH tends to drift up pretty quickly and and usually have to pour acid in ever 10-12 days so hopefully I'll be OK. I'll let you know if disaster struck

Thanks!

I'm about to go on vacation too.

I leave a set of gallon jugs of chlorine with instructions to my father-in-law to add one every other day.

I've found I recycle less by collecting enough bleach jugs to refill from a carboy--half tap water, half LC. The stuff is rated as 12.5 % but whenever I test it, it's 14%. So I assume I have 6.5-7% in the jugs I make up. Besides, my FIL will recycle the empties anyway...

I tend not to worry about too-high chlorine--my CYA is 50 (normal for me for late summer--I push it up to that in the hotter weather) so it can safely go to 15ppm, the shock level, as nobody's swimming.
