I am fairly new to the site. Just got the Taylor 2006 kit and love it. We just had the pool refinished with Pebble Sheen (I think that is what it is called). That was over 30 days ago. One thing I notice when trying to figure out how much acid to add to lower PH is that the chart in the Taylor Kit tells me a different amount than PoolMath. I believe it is because PoolMath takes into account the TA - is that right? SO should I just stick to the PoolMath calculation?
