Initial Reading after new water, 3 bags salt, and Intex SWG running about a month - seems clean.
After reading pool school, I added 3 cups Cyanuric acid, 3 cups baking soda, and 3 cups bleach - 48 hrs later
Didn't add any calcium as vinyl Intex metal frame pool. I am running the Intex SWG 4 hours - manual suggests 2 hours based on volume/temp.
My understanding of cyanuric acid is that it keeps the free chlorine around longer, but reduced the killing effect of free chlorine so you need higher levels of free chlorine. Was my pool dirty before, even though it looked good, and now with increased CYA, do I need higher free chlorine.
