Convert to SWG?

[MartyW]

Thanks Carl,
I do realize I'm still using chlorine. I'm trying to figure out what the advantages and disadvantages are (other than initial cost). I also use liquid chlorine and a Hayward feeder and trichlor pucks. How does a salt system affect things like pH, Alk Cya, etc? I fight metal stains every year. I think they came from my heater.

Thanks, Marty

Marty: What we see here is that people do frequently see a rising pH with SWG systems and end up adding acid or using trichlor pucks. However, the rule of thumb for safe sanitation is the SWG should maintain FC at 5% of the CYA (stabilizer) level. Also, most manufacturers recommend higher CYA levels, from 60 to 80 ppm, usually closer to 80. You'll therefore have to keep FC between 3 and 4ppm consistently. If you have low CYA and your pH keeps going up, Tri-chlor pucks may be the solution. They add CYA and lower pH.

IF your system raises pH and you have to keep lowering it, you MAY see a falling T/A. But frequently rising pH is due to aeration--lots of splashing, water falls, etc. Still many SWG users do comment on rising pH.

I'm actually considering taking the plunge myself. Looking at travel plans and may need an SWCG to maintain it during those times.

Carl, Thanks for the feedback. It gives me a lot to think about. If you do take the plunge, which one would you use? Marty

Ha! That's the question, isn't it? I don't know, but if possible I'd prefer one I don't need electrical permits or a licensed electrician to install, if such a thing exists.

But that's part of selecting: getting what you need both in terms of pool size and how you intend to install and use it.

I have a Goldline/Hayward SWG and have been pretty happy with the unit. The current cell has lasted me over 7 years which is pretty good for any SWG. Another manufacture to look at is AutoPilot and the Pool Pilot. That unit seems to have a lot of features.

I can't imagine life without a SWG and has really reduced the amount of time I spend tending to the pool. As mentioned, the only downside is PH rise but both the Goldline and the AutoPilot have PH control systems that work along side the SWG if you want to go that route.

Which Hayward SWG do you have? I have an above ground 18x33 with a deep end, I would guess 18,000 Gal.. From my research it looks like the AquaTrol would be too small.
