I need help with my first test of season. Last year was our 1st full season using the BBB method. We were amazed at how easy, inexpensive and how beautiful the pool was all season. It is a great method and thank you all for your contributions.

I didn't think we would have the same problems opening this year as we did last year having the BioGuard residues left from previous years. But again our alkalinity is high and CYA 0. Have added about 16" of well water. Here are our numbers. Would greatly appreciate your advice. Thanks, Sandy
