Is anyone there? I haven't heard from anyone since my last posts and want to make sure I am understanding this. I have been reading some other threads trying to find stuff out for myself but am getting more confused in some aspects. I am thinking I am not doing my CYA test correctly though after reading one thread. My test says to fill my pool water to 7ml mark and then take the Cyanuric Acid Reagent and fill to 14ml mark. Mix for 30 seconds and then slowler transfer the mixture into this little tube with a black dot on the bottom. You are supposed to base your reading on the level at which the dot just disappears when viewed from top. Mine NEVER disappears or is cloudy in any way. I am thinking this should change my "shock" cl level from 15 to 10ppm???

I am off to do more reading on CYA...sounds like this is the hardest for everyone to understand by what I am seeing.

Thanks again!
