Went ahead and looked into it, some people have had problems, hair algae growth like crazy. However some people love it. Guess its a split. Now I am not sure if I am getting distilled or spring. But on the red label that covers where the bottle gets inserted into the water machine says this:

"Crystal Fresh Purified Water.Purified by reverse osmosis and /or deionization, filtered and ozanated to ensure quality. Contains purified water with selected minerals (sodium bicarbonate, sodium sulfate) added for taste. Mineral amounts are not nutritionally significant."

I figure this is all good right? I mean I read in lots of places that good tank water has been purified, reverse osmosised, ozonated, etc. Just am not sure ahout the two selected minerals that have been added.

SORRY::: Added this post before I saw that others had commented already.
