Works well.+1. It is good insurance since I too use RO water to brew with and build my water profiles for the specific beer I am brewing. I even put a pinch of yeast nutrient in my starters.

Quote from: mabrungard on June 22, 2021, 04:58:30 amMy experience and research indicates that there can be problems when brewing with pure waters like RO and distilled. Including trace elements like zinc and copper do improve fermentation and finishing. When added in the proper trace amounts, they are imperceptible to drinkers.Also oddly enough, the highly dreaded manganese has a sort of symbiotic relationship with zinc in the presence of yeast, and the two must go together, with manganese at only a small fraction of zinc (which in and of itself is not needed in more than very small amounts). It has been found that when there is no manganese the zinc should be held to less than 0.6 ppm, else fermentation will actually begin to suffer, but in the presence of just the right minute quantity of manganese the yeast can both tolerate and benefit from much higher ppm's of zinc.https://onlinelibrary.wiley.com/doi/epdf/10.1002/j.2050-0416.1975.tb03784.xhttps://onlinelibrary.wiley.com/doi/epdf/10.1002/j.2050-0416.1998.tb00996.x
