I'm new to the forum and am so thankful for TFP! It has helped me immensely as this is my first summer caring for a pool. I'm dealing with a vinyl pool with about 1800 gallons of water. I've had the pool up for about a month, and am concerned because my TA is 210. My pH has been extremely stable (7.5) the whole time the pool's been up. I read on the forum that it is more difficult to adjust pH than TA. Although my TA is so high, am I safe to assume that I should not mess with it since pH is so stable? Will TA this high damage vinyl? Here are my numbers:
FC: 6 (usually swings around quickly between 0-6)
CYA: Little less than 30 (I plan to add a little more dichlor to raise CYA to keep FC more stable since pool is in sun all day.)
Water appearance: clear
Gets lots of regular splashing from kids.
