I was just looking at Gerber pure Baby water it says it purified water with some added mineral for tast its from a protected well in Stanwood Michigan purified through reverse osmosis and distilation no added fluoride ingredents are purified water, magnesium sulfate , potassium bicarbonate , and calcium chloride does this sound like a good source of water and would any of those ingrediants harm any of the frog spieces if used ?
