What do my chlorine levels need to be?

[PoolDoc]

. CYA stays at the top 3 inches of the surface of the pool on a calm steady day. Draining from a skimmer or a scum ledge is the best way to lower CYA if it gets too high.

Uh, that's totally bogus!

As a CPO myself, and a former instructor, I can assure you that that idea is NOT from CPO training. If you got an instructor who taught you that, you got one from the bottom of the NSPF's barrel. Bad luck for you, but please don't dump his goofy ideas here!

It's also not true that

• all pools with FAC at 1 ppm are unsafe -- it IS possible to be 'safe' at that level, or that
• there's something magical about the range between 2.5 ppm and 7.5ppm, or that
• it's impossible to run a safe and sanitary pool with 150 ppm of CYA!

Please, learn more, before you try to post authoritatively. Unfortunately, having one of the nice CPO patches and certificates does NOT make you an expert.

And . . . you need to ID your connection with the industry in a signature line to EACH and EVERY post, which identifies who and what you are in the industry, but does NOT try to 'sell' your services.
