Ah thanks for the insight. However I don't have a car yet and my parents don't delight in driving 10 miles to Walmart so I probably have to stock up big time the next time I go. Which will be a while from now.
But, I *may* be able to convince my folks that the RO system is to be used for drinking water (when in reality I would use it for my tanks
) so they *might* actually buy one for me.
