OK. Do you have an OTO test kit that tests just chlorine and pH? If not, get one. They are cheap--$5-$10, or if there's a Walmart, get the HTH 5-way drop test kit--for $12 to $15 it's a bargain!

Your change is too drastic--that's why we don't recommend strips--it's too easy to make BIG mistakes with them.

Until then I'm not convinced everything changed so much. The ONLY thing you can safely do is add more bleach. But bleach won't change your pH, your CYA, or your CH levels. (actually it CAN change pH but you aren't anywhere close to where that can happen, so don't worry about it).
