They all say inside 9on a sticker) that it is R/O water, so does that mean that i can use it in my aquarium? At the moment, i pay 50 cents a gallon for R/O water from my LFS, and if i could only pay 23 cents a gallon, that would be great. Culligan, or whoever the compahy may be, changes the filters and does repairs weekely, so it is always clean water, but would you use it in your aqaurium?
