Man, I get busy working (it is pool season) and come back to find a locked thread. So, for those trying to decide whether to go for a SCG or not, I offer these links:
link #1 - a comment (about an article promoting SCGs) from the Environmental Programs Administrator for the city of Thousand Oaks in CA.
link #2 - a question from a soon-to-be SCG pool owner about why she must follow very special rules in the Columbia River Gorge area for her salt water pool...and the answer.
link #3 - "Things that manufacturers of Salt Water Chlorinators generally don't advertise"...from the website of TCG, Australian manufacturers of instrumentation for pH, Redox, Specific Ions, Conductivity, Salinity, Dissolved Oxygen, Turbidity and Temperature for Research and Industry.
I don't know of any other municipalities that have actually moved to restrict sewage connections from salt pools as Santa Clarita. I heard Livingston County MI has banned all chloride discharge to the sewer system and multiple communities in Marthas Vineyard MA have done so with the pool, but have been unable to confirm that with links.
My point is not to bash salt, and I apologize if I can across that way. I just want to fully inform people of the whole SCG picture. I'm sure there are a fair amount of SCG owners out there who have never had a problem, never will and are just tickled pink with their systems. But beyond the potential corrosion, which seems to flutuate from area to water balance to pool to what kind of stone work, it seems to me that salt simply is not a very green choice considering all the discussion of chlorides in the environment (I didn't bother with the multitude of links regarding chlorides and water softeners). We all believe in what we sell, that much is obvious to me. I'm just the "Green" choice.
Thanks for the correction about deicing salts, Sean, I appreciate the heads up - my mistake. And there are indeed salt tolerant plants that will weather low levels very well while other plants are extremely salt sensitive. In fact I discovered there are spieces of non-native plants that grow right next to the salted roadways because they are so sodium tolerant. They are spreading quickly into areas where other plants can't live.
As far as being drawn into a discussion with the salt reps or pro-salt pool guys defending the system I represent, no thanks. The thread that got locked was about SCGs, not alternatives. Oh, and I'm not the copper Queen (though I like the capitalization), I am the copper Goddess. And the FTC would've slapped us down years ago, 13 to be exact, if our claims were not true. 8)
