Even at 2 bucks for 5 gallons, the price adds up quickly. I use 10 gallons a week for my tank. So 4 bucks. That is over $200 a year. RO/DI unit was about $150. I have had that for almost a year now. Takes 9 months to pay for itself. Plus now I dont have to lug 5 gallon buckets to and from the store or waste gas going to the store. IMO even on a small 29 gallon tank, it is well worth the investment.
