It lived up to the expectations big time... But the ROI just wasn't there. The two biggest issues were daily maintiance and costs. With a system as large as mine the costs were just too much. Add that with a required 15 minute, twice a day routine... It just built up. As far as the corals go, I had never seen growth as fast as with Zeovit, not to mention polyp extension and coloration. My water was dramatically clearer and I had no nussance algaes.
I'm going to stabalize my system a bit with carbon, rowaphos and maybe some ozone then slowly work back to one of the bacteria systems... either probideo, micro fauna or the new elos. My only concern with these systems is the lack of the zeolith. Maybe I'm wrong, but I thought the zeolith aspect provided a lot of benifitial things, from porus rocks for bacteria growth to ammonia absorbtion... Ehh, we'll see what happens in the next month or two when I decide on what to do.
