Hey kids,

In my new place I am going to need an RO unit and so I figure I might as well get one which does DI as well so......does anyone have any experience/knowledge of any particular brand? I am probably looking for something which will do at least 50gpd

right now im looking at the Maxxima 60 Hi-S (60gpd) and the Pure-Flo II RO Unit (50gpd)

any thoughts?

Ive been looking at Ro/Di units recently for future use and the only one I really wanted was this:

http://www.marinedepot.com/md_viewItem.asp?idproduct=KM1433

Im pretty sure it was the one you were mentioning. ALso on the bottom of that page it talks about how much you have to replace the filters and chambers and it seems like a very good investment for how often the cartridges are changed. Thats the one Id go with but I couldnt find anything about the second unit except at drfostermsith and they didnt really go into it

Actually i talked about this subject with a lot of people in LFS, friends etc and they all agree that super pricey ones aren't very different with cheap ones. Some costs more because they have glass or TDS meter with it. Mine was leaking where there's a bulkhead but teflon did the job. Like the skimmers, they don't really do like 50 gpd or 100 gpd...
Anyways the good things are inside, the membranes, cartridges. I bought coralife 4 pack last week so i guess this is what really does the job.

kahluazzz: just to verify, these attach to a faucet by using a screw on adapter, correct? no plumbing modifications are necessary, yes? i live in an apartment so I can't do anything to the pipes

tammielynz:doing good over here...how about yourself?

nope...the faucet adapter is sold separately. I pierced the tubing under sink with the screw attached to the unit's tubing. I live in an apartment too, but the tubing will cost like 2-3 $ to replace when i leave and i can remove it easily ( attached to 2 bulkheads ) ..the tubing looks like a straw..mine is heavy plastic.

The adapter looks like this :

I believe there is a faucet adapter you can find, however, most that I have or have seen have been undersink installations, requiring a needle puncture into the cold water supply line or a joint fitting installed before the faucet. However, it is important to note that you can ONLY run cold water through these units, anything warmer can damage the membrane and thus defeat the purpose of a RO/DI unit.

That's the one fact I dislike about this, what are you going to do? Water change with COLD water if doing an immediate water change? ... although that would take forever using such low-output units. I just thought of this, but I guess you could possible microwave some water to bring it to a proper water temp!
