I am completely amazed yet again. I retested the top water in bucket for hardness today. It has NO red coloration whatsoever. NO hardness! Unheard of round these parts! But yes, I'd like to make sure to proceed on the pool with somebody holding my hand. Yes, I admit it, I'm very dumb about this chemistry stuff. And with such a high number to start with I imagine I could really screw things up bad if I go about it wrong.
