hi guys, anyone have a good recommendation for a ro/di system. think it wil be my next big purchase. i dont mind spending a tad bit more for some extra bells and whistles, but im not trying to break the bank either. they're just so many to choose from, was thinking of getting a 4 stage one at least. . they have a 6 stage on BRS for less than 300 bucks. i usually do a 2.5 gallon water change on my 30 every week. sometimes 2 twice if im messing round with the tank. the lfs i like to go to is 20 miles one way. so its not close. thanks
