I am considering buying the Intex SWG for this year. I looked at the Intex SWG post but was just wondering how would you close the pool when using one? I read that you don't have to add chemicals through out the season. Also I want to get the SWG before opening the pool so do I just add the salt and start the filter and pump? How would you check if the water is balanced? I know you can use the test strips but everyone on this forum is against test strips. Last summer I went to Leslies and they always checked the water for me. Is Leslie's Pool about to check the water with a SWG? Any information would be great.
