Chlorine Pucks

and they told me that they didn't feel that high CYA levels were a problem as long as they were under 200 PPM!

I'm guessing they either don't own pools, or have other people that take care of their pools for them!! I'm sure they don't see a CYA over 100 as a problem in somebody else's back yard!!

Unfortunately, this is pretty much Chemtura's corporate line across all their brands. I guess if they told the truth about CYA they would loose too much revenue on lost algaecide sales (Not to mention all the sales of expen$ive borax they sell as Optimzier (Bioguard) and Maximizer (Omni, Hydrotech, Guardex, and Sun)! They have 39 different algaecides among their brands and that's just the US market! I thought the only algaecides were either copper, linear quats, and polyquat! (Well there is also sodium bromide and inoragnic ammonia). 5 brands and 5 kinds of algaecide each would only be 25 different products. Is there a pattern here?

Edit: When I was speaking to them I mentioned Arch Chemical's (HTH and Poolife) recent study that showed CYA levels of 100 ppm or higher damaging plaster and they basically discounted it and said that their reseach has shown no problem!
