Cheaper than that betta stuff IMO.
Also some walmarts have a culligan water dispenser....super cheap since refills of 5 gal jugs is like $1.50. You have to shell out to buy the 5 gallon bottle first though.
I went back and there was non with the green capped. There was pink and blue I think. What is it called? There were several empty bays on the drinking water aisle.
