Thanks for the info guys, my r-002 is clear but i will check with taylor. I do my testing twice once with the k-2005 and double check with the hth 6 way and so far everything looks good. When i first started testing(green pool) i only had poland spring water i didn't find any CL in it , can i keep using it?
