You need to be able to test your own water. Order a Taylor K2006 or 2006C (better buy). Not available locally but you can get it through this link:> http://pool9.net/tk/

In the meantime, go to Walmart and see if they have the HTH 6-Way drops-based kit (no test strips!) and get that. If they don't, get an OTO/Phenol Red kit (yellow and red drops) instead. Use it to test and then post your numbers. Also while you are at WallyWorld, get several jugs of their generic 8.25% bleach and a gallon of distilled water. Test your numbers and see where they are today. You may need this chart to help you with the off the scale colors:> http://pool9.net/oto-chart/

Your chlorine levels are based on your CYA level. Having a CC reading of 2.0 is not good. Assuming that you do have around 50ppm for CYA, you need to shock your pool up to about 15ppm. More about the CYA/Chlorine connection here:> http://pool9.net/cl-cya/

I'd just use bleach instead of cal-hypo. In your pool, (I think more like 5000 gallons), each quart of 8.25% bleach will add about 4ppm or chlorine and each cup will add about 1ppm. You can use that as a reference for figuring out how much bleach to add.

How does your water look?
