No Chlorine?

By mid summer 2009 we were struggling to keep the chlorine level functional. In September, my husband opted to guess at what might work and poured a bunch of crap in it. I know there was a gallon of algaecide in it by October. During this time, no matter how much chlorine I dumped in, it wouldn't register on a test strip or when we took it to have it done at the pool supply store. I added a super shock treatment once a day for 3 days, still no chlorine. The alkalinity goes up and the water tests hard, etc. But not a drop of chlorine!!
We opened the pool a few weeks ago. It's been vacuumed and the filter back washed. I shocked it, still no chlorine registers. I have had it. I don't know what can neutralize chlorine that fast. HELP!

I was able to find several posts and answers to my problem within the forum. I will attempt to remedy the situation from what I've read.

The test strips that we were using, two different types, were failing to detect the chlorine. I purchased a $40 test kit and checked the water with it. My FC was fine and so was the pH. The test strips would have caused us to add excessive amounts of chlorine and who knows what else!! Take your water to be tested or get a good kit!! It's worth it.

Standard DPD chlorine tests where you compare the intensity of pink/red will bleach out at high chlorine levels having you think there is no chlorine when in fact there is a high chlorine level. The inexpensive OTO chlorine test where you compare the intensity of yellow will not bleach out, but it isn't accurate and doesn't readily distinguish Free Chlorine (FC) from Combined Chlorine (CC).

The best chlorine test kit is the FAS-DPD chlorine test since it accurately determines both FC and CC by counting the drops (see a demo here ) and can measure to within 0.2 ppm for FC and CC. You can get an excellent complete test kit by purchasing either the Taylor K-2006 or the TF-100 with the latter kit having more volume of reagents so is comparably priced per test and has a more logical quantity of reagents. If you already have a Taylor K-2005 so have everything but the FAS-DPD chlorine test, you can get that here .
