I am so glad you have your own kit coming. Good on you for trusting us and following through. I find it really curious the plant had a cya test, but then I don't know what kind of plant it is. More curious they didn't run Total or calcium hardness. If it were me and I had 50 CYA, I would SLAM and not stop until it was absolutely completed. Post back with the new kit when you can and let us know how it's going.
