Hello, I am new to this forum, so ANY and All input will be greatly appreciated!!! We are getting ready to open our pool up for the season and are seriously considering a SWG, but all the reviews I have read and 'pool companies' I have talked to either disagree with doing it or say it's great. I would like to hear from someone who has had a unit in their above ground pool for more than a year and their thoughts please. We have a 24' a.g. 52" deep, vinyl liner, metal walls with protective coating on them. I have read the rust issues with the caps and understand rinsing them off, and if that is the worse thing then great! We are so tired of chasing this pool all year long! We were told yesterday by a 'pool rep' that 'oh no, he seen a SWG above ground pool after one year and he was able to put his finger thru the side of the pool wall from the rust.... Would like to get going immediately on this. Any help would be so great! Thanks!
