SWG Operation - Lessons Learned

[PatL34]

I have revised the intial post on this thread, to reflect discussions I had with Chem_Geek regarding the SWCG process.

The main difference is that the pH does not rise. It stays steady. This is the anomaly I saw with members mentioning this with liner pools. However with plaster pools the continuous leaching of calcium hydroxide, will raise the pH and so muriatic acid is needed accordingly. My apologies for any confusion this might have caused.

I have a fiberglass pool and have experienced a pH rise with my SWG. It is slow (and even slower now that I have 50 ppm borates in the water) but it is still happening.

Evan,

I suspect that there might be a slight loss of Cl that is not protected by the CYA, even though Richard (Chem_Geek) describes the SWCG operation somewhat as a "closed System". Ex-chemical engineers don't believe in "closed systems".

As Richard has mentioned, there are a lot of loose ends regarding the SWCG process that still need to be tied up. Your experience of rising pH is just one.
