well, i dose cyclopeeze when i feed fish , dennis at dt's , i think thats his name, told me cyclopeeze is too big for sps, not sure if hes trying to push oyster eggs or not................. i also give 6 pumps of liquid life coral plankton , which is dead rotifers, every 3 days to my 120..................i see coral food mentioned alot, was wondering what exactly they are referring to.....................plus im a bit more concerned on this trace element overdose , i read some say they lost corals and had fish get ill, yet others say they use it with no problems.....................i would think perhaps it was used incorrectly, but i dont know since ive never tried it
