New to taking care of pool chemistry on my own after 11 years of relying on the Pool Store. My SW pool's water had a greenish tint for the first time ever this spring. I bought the TF-100 test kit and got the following numbers:
Decided to shock and added 10 lbs of 65% Cal_Hypo (more than the pool calculator recommended, and I know the danger of raising the CH, but it's what I had on hand).
In any event, the pool looks absolutely great now, crystal clear, but the new numbers aren't much better:
Borates: 40 (I didn't have this test first time around).
As I said the pool looks great. I'm in RI, so it hasn't been very warm. So where did all the chlorine go? And do I SLAM again. I have purchased 12.5% bleach if need be.
Thanks from the Newbie.
