Calculate how much you will spend over the next 6 months on once a week water changes and factor in your time to go get water, gas, containers to keep it in and what not. Then go to purewaterclub.com and see what the cost of one of their units is. I went with the 150 gallon RO
. You will need to keep fresh water on hand to top off with and I always have about 15% saltwater made up on hand "just incase".
