I just set up my 15' x 48" agp from Intex. I also purchased the sand fileter pump and SWG combo. The instructions say to add 1.1 lb. of CYA. However, from the poolcalculator, that would only give me a CYA of about 30. Most posts I have seen recommend about double that for a SWG pool. Why the low recommendation in the owners manual? I am currently adding CYA via the sock method, but my test results prior to CYA additions were as follows:
FC - 1.5 in the morning, 0 in the evening (SWG runs at night due to swimmers during the day)
pH - 7.8 (struggling to keep this low enough even using pH minus)
TA - 100
CYA - 0
Salt - 3300
Water Temp - 88
Any recommendations/suggestions are welcome! This is my first post, but I have been spending a lot of time on this forum and all of the info has proven invaluable. Thanks!!
