There is no disbute that Zeo works, the real question is how much money and time do you want to invest? And is the result that much better? The beauty that it brings out of the corals is very subjective. Some may like the wash-out look, and some may not. If you're OK with spending some extra money and time every day dosing, then it's ideal, however to gain true success from it requires long time commitment. I ran Zeo for about 5 months two and a half years ago and saw what it was capable of. I also experienced how demanding the whole process was and quit shortly after. Taking what I learnt about Zeo, I've developed a way of reef keeping that I am very happy with today, and it may even rival the Zeo.
One of the most enjoyable aspect about this hobby is having to maintain the tank as least as possible. Zeo doesn't fall in that category, it requires a lot of nurturing. A high maintenance tank will tend to drive people away from the hobby in long run, it just doesn't last. Keep it low-tech and low maintenance and you will reep the rewards for a long time.
For those who are interested in using Zeo to color up your corals and to manage nuisance algae and the likes, go for it, it works, but beware of the commitments invovled. I'll post some coral pictures of my non-zeo method.
