Help selecting an small volume RO system

[5881]

I searched this site thinking this had to have been asked but did not see much. I am running a BioCube 29, a pico 3g and a Nanocube 6. I guess my water needs are less than 10g/week. I have been using the LFS water @ 1$/g, which is not cost effective and the weekly trips are a drag. I saw a Corallife 25g for about $110.00 at Fosterssmith, then looked here and heard about The Filter Guys and some others,. Would like a "freestanding" unit; just hook it up to the tap, make 20 g or so and put it away. I live outside of Phila., and have city water. Do I need DI? Mostly reef inhabitants in all the tanks.
Thanks for the help.

Hi 5881,

I would definitely get a 4 stage unit with DI. This will provide you with the best possible water. Outside of that, they are all about the same in my opinion and it comes down to finding one from a manufacturer that you can get good service from. My brother got one off e-bay new for like $120 and it worked fine, as does my Aqua-FX that was over $200.
