OK. I've got some from Wal-Mart but it has copper so I've not used it, only bleach.

Thanks for the heads up on using acids. I've used different acids at work and its all about paying close attention and using the proper ppe.

So I'll bring the pH down using half of the previously noted amount and raise the FC levels with bleach to continue the war. Do I take care of the algae and then worry about the other chemicals?

Thanks for your help BigDave -
