The worry I have about it is that I can't find too many people using them on reefcentral or other forums for that matter. When I do find threads on them I see people have the same concern about the wet/dry portion becoming a nitrate factory which is of real concern for a reef tank. Some people do seem to like them and I did find some youtube vids as well showing them functioning and the idea is pretty good.
Here's a short thread on it. Like I was telling you, one of the main components of that system is not being used by too many reefers anymore (wet/dry) and the other (protein skimmer) seems to work but nowhere near as well as a dedicated unit. I just don't think you'd be getting much bang for your buck since reef tanks don't benefit much from conventional filters like canisters and wet/dry and often times those setups can be detrimental to reef tanks.
I hope others will chime in that have either used it or have more opinions on the matter. Just remember it's best to read a ton, then read some more. The more information you have the better your decisions will be in the long run. This section of the forum is full of people that are so excited to get started (and they should be) that they push things too quickly. Often times spending unnecessary money or worse yet harming marine life unintentionally.
Sorry for the long winded responses lol
