I've been searching through the website and the forums and can't seem to find any guidelines on how much FC loss should be expected. In one post you see people say that 4ppm is far too high and something is wrong. In another, they will post that 3-4 could be normal. Some of the more consistent posts have said that about 50% loss (I assume that is the total FC level, i.e. if my target is 10ppm, then I might lose 5ppm during the day).
So my question is: Are there guidelines on what are normal or reasonable FC loss over a 24 hours period? (I know the best way to see if something is wrong is for an OCLT of less than 1)
My FC loss seems to be about 3.5-4 now that I am out of the SLAM, but I haven't done an OCLT is about a week, so I will do that again.
Last nights numbers: FC - 8.5 (9.0 target), CC - 0, pH - 7.8, CYA - 80, TA - 240 (pool guy said this is mainly due to our water, but I am starting to try to bring this down)
