I purchased a house recently with a pool. It was a beautiful deep green algae color(the pool not the house). I had a pool "pro get me started. It is now pretty clean. I feel I am on the home stretch. I finally purchased a taylor k2006 test kit and tryed it out.
fc 5.5
tc 5.5
ta 120ppm
cya 115ppm (uh-oh)
ph 7.8 ( a little high)
ch 230 ppm.

My pro had me use the wonderfull pucks. I suspect this is where my high cya #'s came from. I have been using clorox bleach since i discovered this forum a month or two ago. I have not had to use much (I believe because of the cold weather.) I am no longer using the pucks.
From what I have gathered the only real practical way to lower cya's is to drain a portion of the pool and refill. Is this correct?, Am I missing anything?
I feel since my cya is so far off this is the first thing to fix before I adj ph.
Any comments or questions are welcome Yhanx everyone!
