Hi, thanks for all the great advice. I believe my last cya was at 20 and can't remember if i put more stabilizer in or not. I will recheck today.

I did find that post on how to test without a good kit and will try it today.

I went to wal-mart this morning and got 15 gallons of bleach at 1.27 ea. Do you think that's a better price than the chlorine at 3.50 a gal? I know i would need less but will it all work the same?

thanks again
