and get a good test kit ASAP:
HTH 6-Way Test Kit @ Walmart
Taylor K2006A (3/4 oz bottles) @ Amazon
Taylor K2006C (2 oz bottles) @ Amazon
We're seeing more and more cases where both BioGuard and Arch / HTH products are CREATING the problems they will then sell you fixes for; it's definitely becoming much hard to get plain unblended basic pool chemicals with few side effects. I can't prove they are doing this on purpose, but . . .

If you can't get the HTH 6-way immediately, at least get a cheap OTO / phenol red drops kit, and check your pH.
