Hey all, I will preface this by saying this is my first winter with my pool so I’m still trying to get the hang of things. I went to test the chlorine today and my water turned pink indicating that there is chlorine but my salt water generator says “cold” indicating it’s off due to temperature. I haven’t added any liquid chlorine since my pools temp is 42 degrees. Is it possible something is wrong with my testing kit or that there’s residual chlorine from a few weeks ago when my SWG didn’t say “cold”?
