Do these things:

1. Get a cheap local OTO test kit (yellow / red drops).

2. Add sufficient bleach each evening to have a dark yellow OTO result in the morning.

3. Test the pH in the evening, BEFORE adding any more bleach. Make sure the pH is between 7 and 8. Otherwise, don't worry about it.

4. Once you're caught up on your bills, order a Taylor K2006 from Amazon (link in my blue signature block). Once you have the kit (hopefully, before you close) report test results here.
