Quick question. I have mixed SW ready for the past 7 days....I usually mix up RODI/Salt mix and use in about 2 days - is 7 days too long? Should I mix up a new batch? Thx.
I would check KH too. Some of my mix was testing high, but it was sitting for about 5 days. The threoy was that is the O2 exchange wasnt great enough, co2 was high or had rissen, the bicarbonates were breaking down, raising KH.
