Hi everyone! I've never owned a pool before, but have really enjoyed reading this site!!
My pool became slightly cloudy a few days ago, so I've been adding chlorine. This has worked great, and I'm about 95% clear. However, when I test using the "add 5 drops and see how yellow" method (got the TF100, so much better!), the water stays completely clear for a few seconds, and then starts to get more and more yellow. ISTR the instantaneous is FC(?), and then a while later you're actually looking at something else (CC?), is that right? Before the cloudiness, each drop would be a bit yellow right away.
Anyways, here are my readings:
Here's the "add" portion of my log:
6/13/2013 19:30:00 add Added about 100 oz of 10% bleach
6/14/2013 10:00:00 add Added ~300oz of 6%
6/14/2013 21:00:00 add Added 128 oz of 8.25% bleach
Am I adding bleach too quickly?
Also, since the pool cover is open less than an hour or two a day, I wonder how long I can stay at a really low CYA? I've gone through a 7 lb tub of 3" Trichloro chlorine tablets already last month (which add CYA, right?), so I don't really think I'm at 0 CYA. Is there a benefit to staying super low?
