Is there any sort of a "primer" on this whole SWG subject - I keep seeing references to them, but am not really clear on what they are / how they work / what they do and so forth... Obviously they make chlorine, but... It might even be worth a sticky?
Some of the questions that come to mind...
1. How salty are we talking about making the water - is it on the order of measurable but not noticeable to swim in, or is it like going to the ocean instead of the lake? How much of a problem is the salt going to be if one just backwashes out on the ground (like I currently do with my DE filter) (i.e. will it kill my grass / trees, pollute the ground water, etc?)
2. In general numbers how expensive is it to put one in and run it? How does this compare to running straight "pool store" chemistry or BBB? How do the cost / amounts of chemicals involved change? What does it cost to run one in added electricity? What about parts to keep it going?
3. Does it cut back on the amount of time needed for testing / working on the pool?
4. I've seen discussion about turning an SWG down / off in the winter, but the people doing it were still leaving their pools set up mostly - what about those of us in the frozen north lands that have to tear everything down, blow out the pipes, etc. to avoid freezing in the winter?
5. What sorts of changes to plumbing / electrical are needed? Currently I have two 15A 110v circuits to the pool, one for the main filter pump, one for the Polaris booster pump, each is controlled by an Intermatic timer next to the breaker box - would these work, or would I need another dedicated line (which would get expensive, as my breaker panel and conduits are both full....)
6. Any other stuff on the upsides / downsides of having one that I haven't thought of, but that you'd tell a person considering the idea?
