Wow, we call that being "pool-stored". As Dave said, you'd be doing yourself a HUGE favor to get your own test kit and run away from your pool store. The kit is easy to use, reliable, and doesn't have selling you more stuff to throw at your pool as a motivator. It can be gotten at a really good price online, or through the link in my sig.

The reason you're not getting a chlorine reading is likely that the chlorine levels are probably bleaching out the strips. In most cases, strips are good for telling you if there IS or IS NOT chlorine in the water, but not reliable for telling you HOW MUCH. And in cases of high chlorine, they bleach out and are completely useless.

I also have a problem with the test results that you printed out from the store--they appear to be computer-generated results that were acqured by reading strips. No CYA test that I know of can discern a CYA level less than 30 ppm, so I especially don't trust that one. If you have a pool store near you that uses drop-based testing, then try taking a sample there.

You also need to decide, as Dave mentioned, whether you want us to help you get it cleared up, or whether you're going to go with the pool store advice. We don't mean any offense, but quite often our advice conflicts with what pool stores advise, because we're giving advice based on tested, proven methods in our own pools, not advice geared toward selling you anything. So..if you try to merge advice from both places, you'll likely be wasting time and your money, and frankly, we are at the peak of our season so time is sort of critical when we have so many folks needing help. I know that we can help you get it swim-ready, we just need to know if that's what you want us to do.
