I would like to buy an ro/di system that is at least 75gpd. I have spent most of my money buying the tank and other equipment, so I can't really spend more than $80, but if I have to will spend up to $100. And I know this is a pretty low price for a good ro/di system, but I really need one so I can get my 120 gallon setup. So if anyone has an extra one laying around, or they are getting out of the hobby please let me know. I could really use one. Thanks!
