My pool is salt so I was running my CYA at 70-80 range. Last couple of month my SWG is not working so I am manually chlorinating water. Doing a test last week I noticed that my CYA is at 30, which is withing range for a manually chlorinated pool, but I just realized that CYA should never go down unless you replace water (which I haven't)
Could CYA go down overtime by itself only with water evaporation and some splashes?
Thank you.
