Just getting started with this BBB method and have a few questions about testing for CYA. Bought a Taylor K-2006. It says CYA is way high at around 150. Pool is starting its third season and I have learned that I have been making some rather large mistakes as far as what chemicals to use for what. Had a small problem with algea late last season and after much reading here suspected the CYA issue. My questions are 1) does the water temp affect CYA results? Water is still very cold at about 40°. 2) What are options to draining if test is correct? I only have well water and would prefer not to drain.
