 depends on the carbon and the coral.  zoos and palys are kinda sensitive to large ammounts of carbon I've found.  A large ammount, I've found, is like a liter of silicarb per 100g.  I now run my carbon passive like the zeovit guide says.  100mL / 25g
when using silicarb use about half as much.  That stuff's SUPER strong.  I made the mistake of using an entire bag for my 120g tank in an AC HOB filter and it did a real number of my soft corals (toadstools, zoos, finger leathers, palys)
