is the Aquatic life ro buddie good to use in a reef tank

I bought this for use with my nano and have been using it for about 9 months, and it has really paid off. It takes about 45-60 minutes to fill a gallon, but since I'm only doing 2 gallon WCs a week, it's perfectly acceptable.

I use this 3-chambered version exclusively, and my nitrates currently read at 0-5ppm, depending on how long it's been since I did serious maintenance on the tank. I was wondering if I should get the 4th chamber DI attachment when I got this kit, but I think it's fine on its own.

If you are planning on doing an SPS tank, I would recommend getting the 4th chamber attachment, but for everything else it should be fine.

thx! Im in the process of setting up a 55 gallon, and for now just planning on soft coral to get a feel. later plans would be to move up LPS and SPS.

depends..
The one with the DI stage or not?
How many GPD does the one you are looking at do?
What is your incoming water TDS? <--important (get a TDS meter first to verify)
What is your incoming water pressure? <--important too (get a gauge to put on the hose bib to check)

How much water do you want to make?
Do you mind wasting more water than a "better" system? (ro buddie has what a 1:4.5 rejection rate which means for each gallon of "good" you dump 4.5 gallons of "bad" down the drain (or into a flower bed,etc..)

Do you want to drink the water too from a drinking faucet?

In reality a "good" RO/DI system is worth the extra money.. Check out the systems at bulkreefsupply or airwaterice or buckeye hydro or spectrapure and one other vendor of this site that I'm forgetting (sorry guys)..

Things that are good to look for (and almost can't live without)
#1-high rejection rate RO membrane (higher the better in general)
#2-Includes a dual TDS meter
#3-All full size (2.5" x 10") filter canisters including the di stage.
#4-ASOV (automatic shut off valve)
#5-Good carbon filters for chloramine removal (if your city uses it.. probably does now)
#6-pressurized tank if you want drinking water too

The often quoted 4 to 1 waste ratio is from data from the membrane manufacturers in terms of what is needed to get a reasonable life span from the membrane.

For an RODI ideally you'd have a 3-probe meter - the TRM1, rather than a two-probe meter.

ASOV only needed if you want to automate the system shutting off and back on again.

At this point only about a third of the water supplies in the US use chloramine.
