CYA (Stabilizer) Minimum FC Target FC Shock FC
60 5 7 24
I assumed from this chart that if you keep FC between 5 and 7 you won't have algae.
However I have found algae can grow well at 7 FC. Yes can treat with shock, again,
but would rather understand why. Is it better to have a higher target FC level, say
12 FC. Would that buy me less algae?
My current thoughts, please advise if any/all need correction:
-- algae will not grow at FC 24
-- algae grows rapidly if FC under 5
-- at first sign of algae, bump FC to 14 and run pool cleaner each day til no visible algae
-- FC above 10-12 is not well liked by swimmers
