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.

Re: SWG Operation - Lessons Learned
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.
