R/O system?

What is a good system? Do not feel like buying jugs of distilled water anymore so can someone recommend? I know nothing about these things.

what about this? http://www.amazon.com/dp/B0006JKO9W/ref=asc_df_B0006JKO9W1872650?smid=ATVPDKIKX0DER&tag=pg-938-17-20&linkCode=asn&creative=395097&creativeASIN=B0006JKO9W

AquaFx, Coralife and Kent all make good systems.

I highly recommend you get a TDS counter as well, this will give you the Total Dissolved Solids in the RO/DI water, an indicator if you will that it is working correctly and when it gets time to replace the cartridges.

Another thing to consider is a Float valve as well to shut the system off in your water collection pale when it reaches fill level.

I just installed this system for someone and it is very very good.

AquaFX Mako RO/DI Unit - 100 GPD : Reverse Osmosis Units

10g Fry / Hospital / QT tank (as needed)

75g Saltwater Reef, Ocellaris Clownfish, Lyretail Antias (baby), Lemon damsel, Longtail Fairy Wrasse, purple dottyback, snails, crabs and a few LPS corals.

220g Still sitting empty (come on Lottery I need the numbers to come up!)

I've seen a couple online that have 20GPD capacity that you can hook to your kitchen faucet. But I don't know how good they are.

Majority of them do not come with a DI unit but they work well if you have a nano tank. TDS meter shows them to be not the best but still in decent levels compared to straight tap water.

Check out this site...they offer quite decent ones.eBay My World - titanwaterpros

with my air water ice RO/DI and living in a city, i get 0 TDS. i have their dual inline TDS meter which shows what your TDS is coming in, and what it is going out which is good to know so you can get a better idea when to replace your filter membranes.

also, from what ive heard the kati ani is supposed to be one of the best.

You can add an inline DI for <$20 if your unit doesn't have one. $34 to add a canister DI unit that is refillable. As far as which is best...I'd say they are really all pretty comparable. I mean the housings are all generally the same, probably most from the same company. I think that the difference in quality will come from the filters used and even then, I don't know that there would be a huge difference. I have one from AirWaterIce and it's a decent unit.

I will say that if I were to buy another one, I'd get one with clear housings. That way you can see how the filters are looking. They are a little more brittle than the white housings but it's not like these units should be getting banged around anyways. The Filter Guys have nice units at decent prices.

my airwaterice has clear chambers.

the reason i say kati ani being the best is because there is no waste water and you can recharge the filter media.

You beat me to writing the post...

They smaller ones are on back order at the moment (smaller being 100 and 200 Gallon) models.

A lot of people have mentioned them on various saltwater forums so they have to be good.
