If you ever do get this going, the first thing that needs to happen is the banning of terms like ULNS or low nutrient. Zeo tanks have more "nutrients" in them than nearly any other tank... they just don't allow them to accumulate. There is a huge difference here that if all reefers understood, then the hobby would be easier for all and advice on the board would be better.
Zeo can be hard because nobody runs it the same way, it seems. All tailor it a bit to their own needs and there is no universal way to apply. If one thing can be said about all Zeo users, it is that they all have an acute knowledge of their tanks and what their tanks need. I have often supposed that anybody with these skills can be super successful with any method that they choose and not just ZeoVit... that is is the dedication, patience and understanding that makes them successful.
