Thanks for adding the HTH pucks Carl, I forgot about that recent "enhancement" to their product.

Another heads up....I've seen pucks at Sams Club that said nothing about copper in the ingredients but a 40# pail was $10 higher than the 'regular' pucks and had some words that escape me but implied 'extra' action of some sort. Anything other than plain old pucks should be avoided. I do use them periodically when CYA needs to be increased.
