I checked at the LFS and they charged 45cents a gallon of RO/DI water. So about 40 bucks for my 80 gallons. If the DI unit is only $40, I might as well invest in one. How much would a good one cost, what brand should I look for and how would I hook it up to my house's drinking water? Some more info would be great!
Is the DI part of the process just another filter? I was planning on buying a single canister and putting a DI filter in it after the water has passed through my RO filter. Is this how it is done?
