I have been on the zeo band wagon for about 16 months... All i can say wild caught aussie acros love the "0" nutrient levels but all your aquacultured acros will suffer... Many of those threads in the zeo form have wild caught colonies and those tanks are over seas. ... The prize is the us are the high end aquacultured frags sold by vendors..we know what to expect when these frags grow and its easier to keep a pest free tank when a tank is started by aquacultured frag and maintence is much easir... No tumbling stones, no daily addivited . No extra reactors ... Keep it simple... Fish, protein skimmer, carbon , live rock , shallow sand bed , A refugium and a filter sock .
