Paperman:

If you are not a dealer then, as you say, no harm, no foul. And thanks for the info.

It would be nice to learn the Arch at least still makes the GOOD ones for SOMEBODY! They and WalMart don't seem to be able to agree who is responsible for the 48% effective chlorine becoming the "standard". At least it's not clear to me. Wally world has SO much purchase power they can force companies to change their products even to the detriment of the supplier and the consumer.
