As noted in my email:

The unfortunate reality is that you've been "pool-stored" and there is no instant fix.

Here's what you need, that you can get today:

http://www.walmart.com/ip/HTH-6-Way-Test-Kit/17043668 - HTH 6-Way Test Kit
http://www.lowes.com/pd_206474-34228-CR.MA.P.01_0__ - Muriatic acid

You'll also need some safety glasses (or sunglasses) and some of the blue nitrile plastic gloves (Lowes or Walmart)

If you're at home, turn your pump on, and leave it on. (It may, or may not, help -- depends on how small the calcium carbonate particles that formed are.)
Post test results as soon as you have them. Your membership has been updated.
