New pool owner, need help getting water right

[PoolDoc]

Don't panic -- I'll probably end up moving some of these posts to the China Shop section -- but I'm just collecting references here, regarding use of N-chlorosulfamate in pools:

Just found this:
"Sustain Summer Shield Chlorine Extender is the brains of the Sustain System. It's not only smart, but unique to PPG, protected by a U. S. Patent."
http://www.ppg.com/chemicals/askjoep...60_summer.aspx

If you can find the patent number, I can tell you for sure what's going on, and how to manage your pool.

Wow thank you so much for the information & the research you are doing! On the bottom of the 3" tab container & the energizer tablet container it says Pat# 4,732,288 & Other Pat Pending 4,967,926. I don't see anything on the summer sheild I don't see anything.

Wow! PPG claims their "Sustain Summer Shield Chlorine Extender is the brains of the Sustain System. It's not only smart, but unique to PPG, protected by a U. S. Patent."

But here are the patent numbers you provided:
http://www.google.com/patents/US4732288 : "Child-resistant molded plastic container lid for open head containers"
http://www.google.com/patents/US4967926 : "Child-resistant molded plastic container lid for open head containers"

No patents for chemistry. How bogus!

If you could, do this:
1. Check the Shield container, again, just to be 100% there is no patent listed.
2. If not, call the customer service number on the container, if any, and ask them. OR use this contact form: http://www.ppg.com/chemicals/askjoep...contactus.aspx

Say something like this, "I use the Sustain system, but it's kind of expensive, and I'm being told that it's probably a bogus system, and not worth the money. They said the patent numbers listed were for the CONTAINERS, and not the chemicals, and that you may not really have patented chemicals. Can you tell me what the Sustain patent number is?"

That will freak them out, and is much more likely to get a response, then if I ask.

The only number I see on the summer sheild is L289A-200B. The sheild energizer 3/4" tabs has a few numbers EPA Reg No 748-286, EPA Est. No. 58401-IL-1, PPG Product# 98994, LP20TSUS-0911E, ESL051811 REV093011 & the 3" cholorinating tabs EPA Reg No 748-275, EPS Est no 58401-IL-1 PPG Product No 38784, LP16TSUS-0911C, ESL051911 REV 093011.
I also sent them an email asking for the patent numbers. Thank you again for your help!

They emailed me the MSDS sheets. Can you tell me how to post an attachment? I do not have a button that says manage attachments.

[PoolDoc]

email them to me. [email protected]

Were the MSDS sheets in response to your email requesting a patent number? If so, their patents are probably the expired ones Chem Geek found.
