Call around and see if there are any pool stores near you that use the 'disappearing black dot' test for CYA. If someone does, have them test your water and report the reading. Just don't let them talk you into buying a bunch of stuff while you are there. They will try!

Your test kit is a DPD kit and will bleach out at high chlorine levels. Go to Walmart and pick up a cheap OTO/Phenol Red kit (yellow and red drops) and use that to test with for now. It will not bleach out. The scale only goes to 5ppm on the OTO kit but you can use the color matching chart at this link to help you decipher the off the scale colors:> http://pool9.net/oto-chart/ Try and keep your chlorine in the dark yellow to orange range.
