I added about 4 pounds of CYA to my pool(14000 gal) a few days ago and tested this morning for the first time. I am still using the Aqua chem test kit from wal mart(I think its the 6 way kit) and the test didn't show any level of CYA at all. This is the type that you add the water till you can't see the black dot in the tube. I know this is a cheap test kit and I am planning on investing in the TFP kit from the forum but shouldn't I have registered something? I am shooting for a # of about 30ppm and had zero before the stabilizer was added. What do you guys think?
