I have a new 2,200 gallon, in-ground SWG spa. Having read much of the info in Pool School, as well as info in this subforum, I am a bit confused on optimal target levels for certain chemicals. To be specific:
From the Pool School articles, the following for SWG pools/spas have been suggested:
CH = 350 - 450 ppm
TA = 60 - 80 ppm
CYA = 70 -80 ppm.
However, in an article by Nitro in the subforum, the following have been suggested (for SWG spas?):
CH = 100 - 150 ppm
TA = 50 ppm
CYA = 20 -30 ppm.
Since the differences are substantial, I would appreciate some clarification.
Thank you kindly.
