I have been testing the Bio-Active CYA reducer and filming the results. Working on a new video in which I am testing it in six pools like the manufacture did for the back of the packaging. I know the stuff is working because the Turbidity test solution is not as cloudy on the follow-up test but getting a spot on CYA reading is tough.
I suspected there was some interference with the results in some test pools and called Taylor Technologies. The Chemist assured me nothing will interfere with the Melamine solution. I mentioned Combined Chlorine or a high pH and he said that this has no effect on the test. But there must be something in certain pools that won't allow me to get a good follow-up reading and I stumbled upon this article by Doug Latta on possible interference. I am going to test his theories on my route and see if it helps get a more accurate turbidity test.
In case you are wondering the results are good but not nearly as good as the manufacturer posted results. The test is of course somewhat bias as to when the dot disappears and also the guy at Taylor mentioned a few common sense things that could throw off the test like dirty vials or getting a sample from a dead spot in the pool.
Not withstanding that and retesting several pools I am getting a CYA drop of 40 ppm - 80 ppm but in one test pool the results were negative. The Bio-Active seems to work but not as well as the manufacturer states - which is pretty common.

If you are interested in my Blog article on Bio-Active here it is - I am updating it soon after I finish more testing.

And if anyone is also testing this product let me know if your results are good or bad.

That is good to hear. I think that Combined Chlorine also effects the products effectiveness - the manufacturer noted that the microbe can also bond with the chloramines in the water and not the cyanuric acid and it is one theory why it doesn't seem effective in indoor pools. I am getting good to fair results in my testing also. It does drop the CYA levels so in that regard the product works. Thanks for your input.
I have been experimenting with it for about 10 weeks now and find that as long as FC, and CC levels are less than 3 PPM, PH is 7.0 - 7.6 then it works VERY well. High chlorine, High PH stop the microbes and enzymes from working.
I keep thisulfate in bulk to control chlorine levels. Typically people with high CYA also have high FC and sometimes really high CC.
