OK. I did a full test of my water yesterday (including borate level). Everything good, combined chlorine was .2 My combined chlorine has been .2 for about the past five days (I've been testing daily because I'm obsessive) Borates were 36. I added 3 boxes of Mule Team (plus the associated muriatic acid first). Last night I only tested the borate level and it was 46. This morning I did a full test and now I have 0 combined chlorine. The free chlorine level was 2.2 yesterday and is now 2.4. I haven't changed the output on the chlorine generator.
The only thing I did between testing yesterday and today was topped up the pool wth about an 1/2 inch of tap water and added the muriatic acid and the borax.
Where did my combined chlorine go? Can MA get rid of it, or the borates, or the fresh water, or some combination of all three??
