I am considering setting up a 150 gal reef tank.
It seems like having a RO/DI unit in the house would be best.
I have seen several brands; Captive Purity, Kent marine, Sea Chem and Spectrapure.......
Does any one have any recommondations / do's/don'ts/ Pros / cons of any of these ?
Thank you for your time

Water General makes a good unit RD-102, double o-rings and solid construction. In my case my tap water tds is high so I went with a full size di canister from BRS and also I needed a booster pump. Really any of the RO systems are good you just need to check what membrane is going to be in it, that's the workhorse.

Steve - Here are some things to look for in a good system for this hobby:

No more than 4 stages (sediment, carbon, RO, DI) unless you have specific water quality issues you want to address
Standard-sized prefilters, membrane, and DI cartridge
Brand name, high-rejection membrane
Specifications provided for each stage
Pressure gauge after the prefilters and before the membrane
Thermometer
TDS meter (handheld or in-line)
DI bypass
Vertical DI stage
Refillable DI cartridge
Aluminum bracket
Quick connect fittings
No water from pressurized storage container delivered to DI
Flush valve
Clear housings
High-quality instructions written in clear English
Customer support before, during, and after your purchase
A vendor involved in your hobby


Some other things to think about:
How will you tap into your home's plumbing?

What will you do/how will you control the DI water?

How much storage capacity will you have?
