then click on bleachcalc262.exe to download it. Don't know why it isn't working like it ususally does.

You need to use plain , unscented bleach. the scented bleaches are NOT EPA approved sanitizers. I would get a drop bases test kit ASAP. YOu can get a decent basic one at WalMart for under $20 that will test all paramters except free chlorine (and there is no easy way to test shock levels of chlorine with it) that will get you by for a while but you really should invest in a good kit like the Taylor K-2006 or the PS234 sold on the sister website to this forum www.poolsolutions.com
It is a much better 'bang for the buck' than the Taylor kit!
