Thanks everyone for your responses. I will order some taylor reagent. I just bought this kit and have never actually tested my pool for CYA so when my first test came out zero I thought I did something wrong so I did it again and came out 0 again. I put some stabilizer in and now I am at 35. NWMNMom stated that you only get 2 test out of it, I got 4 out of this one, but now I am out.
