SWG Operation - Lessons Learned

[Spensar]

Very interesting. Are there considerations for winter storage in the North with several months of below freezing temperatures?

On Ebay I see there are several for $500 to $700. Any particular brand recommended? I saw Hayward Aquarite, The Pool Thing, Zodiac and Pentair for sale in that range.

Any caveats or raves or are they all about the same? Does one use the cell up quicker? Warranty and service support issues?

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.

Good question. I just closed my pool in the Northeast, and it's my first year with the Autopilot. 2 questions:

1) Do any of you bring your cell manifold assembly inside for the winter?

and

2) Since I have the Autopilot control assembly in my shed, I would not be able to bring the cables inside. How would I winterize the cables if I remove the cell manifold assembly (I was thinking in tightly sealed plastic bags)

[PatL34]

Tightly sealed bags should be sufficient. When re-opening in the summer, use a hair dryer to dry out the tri-sensor and cell connections on the cables and the cell manifold assembly.

Pat and Waterbear, (this is only ~ 4 mos late) Re: posts 34 - 36 on this thread - why didn't you ask me???? - I have access to large quantities of vynal liner stock, salt and the best test kit. If you'll give me the specifications for the experiment (I think I know what is required, but would rather you tell me how to set it up to get your required results ie., volume of water, ppm salt, sealed or open, what would the control be?, etc), I'll gladly perform it.
If this is now a 'non-issue' that's fine, but if you want me to do this, I'll need to know in the next week, as I'll be layed off in the next 2 weeks (aaaahhhh, winter!)
