Thought I would get some of the expert opinions on this one. I did much research and talked to the reef gang and this came highly recommended:
It is a 4 stage system with a complete drinking water kit (3+ gallon pressurized tank, sink faucet, etc). It does not have DI, but according to the research I did on terraforums, it will make water that is plenty pure for carnivorous plants... should easily get me under 10 ppm. Oh yeah, I was pleased to find out that it is a 75 GPD unit... and it looks like it has really high quality filters and parts. Complete filter replacement kit is only $31.
