Hey guys, my apologies in advance if this was posted in the wrong place.
Tonight, I was racking one Carboy while starting a new batch in another. In between finishing the first Carboy and sanitizing the second, the color of the water went from a pretty dark Amber color, almost completely back to clear water. There was almost no noticeable tint. It had been sitting and sanitizing other equipment for about 45 minutes - 1 hour at this time. Just to clarify, this was in my garage during the night, in around 70 degree weather using room temperature water.
So my question is, if Iodophor looses its color within that short of a time span, is it still effective, or am I going to end up dumping my new batch?
Do I need to continually dump iodophore in to maintain its color? or is Star San more effective for longer periods?
Really appreciate anyone’s help on this, thanks!
