I've been a lurker on this website/forum for a few weeks now, due to having problems with a green pool. Followed lots of tips + advice on here to get my pool water clear again. It's taken a few weeks, using a rubbish dip-test kit while waiting for my Taylor K-2006 to be imported from the US! I've basically been replacing water due to a high CYA reading (150ppm) and adding random amounts of liquid chlorine. I now have my Taylor K-2006 test kit! (FAS-DPD)
I have a question about the CC test. When I add the R-0871 reagent, after I added the first drop the sample turned colorless after a little swirl, indicating CC 0.5. After about 10 seconds, the sample turned slightly pink. So i added another drop and it turned colorless again (2 drops = 1.0 CC). Then another 10 seconds went by and it went slightly pink again. I got CC 2.0 then stopped.
Should I wait until the sample stays colorless for longer? How long should I wait?
The pool is still a little mirky, and has a green tinge to it. I can see the bottom, but not 100% clearly.
CC: 0.5? 2.0? More? Not sure
Going to re-test first thing tomorrow a.m., to see if the FC/CC has changed.
I realise that I need a FC level of 24 to keep SLAMing - but couldn't manage to get to the store to get more chlorine today.
