I dumped in 4lbs of Stab and these are the results after two days:
100 - slightly cloudly, easy to see the dot still
50 - cloudly, barely see it, but still can
40 cloudly, really barely see it.
35 - if you look hard enough, you can see it.
30 - gone, but you know its there.
So what number should I go with based on those? PoolMath was dead on by the way. It said I needed around 8lbs to get to 75 CYA. I just wanted to start slowly.
Also, pH leveled out as well, intially it went too low, but now its hovering around 7.5-7.8. FC is the next issue, now that I have CYA, I wanted to hit it with Liquid Bleach.
My crew is coming out today to dump in 20lbs of salt, not sure if it will have any effect on Stab or Liquid Chlorine?
