RODI System

This one is much cheaper than the others I have been looking at. Anyone have any experience with it? Missing anything important?

Looks ok to me! The thing with an ro system is 'In my opinion' you want to buy one that's been around or made by a known manufacturer so when you need to change parts like your membrane, youre able to find the parts easily and can be confident theyll fit. Unless im missing a huge fact that most of the parts can be universal to whichever ro system you buy.

Fish die belly upward and rise to the surface. It's their way of falling.

Most full size units have interchangeable filters, there are some exceptions though.

I have a mix of many different saltwater fish amongst my tanks, but I love my Tangs most of all.

We are admittedly a bit biased, but here's some things most people would find less than desirable:
Unless you have chloramines in your water, why do you want a system with two carbon stages?
This system has a horizontal DI - a fundamental design mistake.
The ebay listing says 18 oz of resin will refill the DI 3 times. A standard DI cartridge will hold 20 oz of resin rather than 6.
The system will route water from the pressure tank through the small horizontal DI - another design flaw.
You'd be better off with a 1 mic sediment filter
The system does not have a pressure gauge.
Has a low rejection 100 gpd membrane
No spec's provided for the carbon blocks so you have no idea what you're getting.
It has the old fashioned Jaco compression fittings rather than quick connect fittings.The system doesn't come with a TDS meter.
Looks like they have the spec's wrong for their membrane...makes you wonder.
The housings have male threads on them and are prone to cracking, especially on the clear housing.

Other than that, it looks like a steal! Bottomline, you get what you pay for.
