I am guessing most of you guys do it this way... but say you have CYA of 50, and the target FC is 6. do most of you keep the FC at 10, and let it drop? At least this is what I am doing... though my CYA is way above that... just an example..
well.. mine drops a bit during the day as the sun is on it fully from 7am till 6pm. so leaving it only 2 above would be in danger by time I got home... It passes the over night test... just loses a lot during the day... esp if it was windy and lots of leaves get in there.
At least this is my explanation of why i do it. I did read some one raises theirs to shock level before people swim in it... IE party or such.
didn't realize the there was a % part to it.... it just drops 3 or 4 a day.... depending.
