ok. So I'm safe as long as I use eye protection and follow your precautions. We have a Lowe's 5 mins away. I just (within the past few hours) added 18 ounces of the pH down. Can I retest and add muriatic acid today, or should I wait until tomorrow? How long after I add the acid can I add bleach? Also, how long after adding the acid can we swim? A few hours? The next day? And, where can I buy replacement CYA reagent for the Walmart kit? I don't really trust the strips for the CYA, and I am not sure if I am keeping my chlorine high enuf, based on how much CYA I (think I) have.

Thanks so much! Sorry for all the questions. I am really not a dumb (graying) blonde, but when it comes to this pool chem, I often feel like one.
