Ingredients / Re: Is StarSan less effective if hard or alkaline water is used?

I almost always use RO water for my star san. Stays good for months that way. High alkaline water will certainly reduce its effectiveness over the long haul, but is surely good for 12-24 hours or more. My rule of thumb has been "once it turns cloudy, pitch it". Though the pH rule is more sound.
