RO unit question

[Hetfield6j]

I have been looking at getting a RO unit for a few weeks now. Been looking at getting the Coralife Pure-Flo2 from a lfs but i have a few questions. First, the unit doesnt claim to be a RO/DI, but specifically says it has a Deionization filter. Also, it says its 3 stage, but with the membrane on the top shouldnt it be four stage? Any help on this would be appreciated, and any experiance with this unit. Thanks.

If it has a deionization cartridge then it's a DI. Take a look at www.airwaterice.com . They have some nice units. Recently bought the MightyMite from them. Excellent customer service.
