I'm brand new to this forum, so sorry... my questions are so very basic.
We bought a house last fall that has a 15' above ground pool with a cartridge filter and using chlorine tablets for treatment. We drained it down a bit as they instructed us and covered it for the winter as they recommended. To open it for the summer, I would like to put in a SWG because of skin sensitivity to the chloramines.
When I asked about SWGs at the pool company that installed the pool, they strongly discouraged me and recommended Softswim (Baquifil?)as an alternative to chlorine. They said SWGs "will corrode your above ground pool in months", "too much chlorine is generated", "doesn't work well for above ground pools". They also suggested UV/ozone but said it would cost over $2000. None of the is consistent with what I am starting to research.
So my basic questions:
Are SWGs a good alternative to chlorine? Best Brands (Haywood vs. Pentair?)
Who do I believe whether corrosion is an issue for above ground pools?
I have read that a sacrificial anode reduces the impact of corrosion. Is that true?
Do I need to drain the pool completely for fresh clean water to start? Pool company said that might cause the above ground pool to collapse.
