Sicce affiliate aquaLife has a new coral amino acid blend available for sale that promises to enhance coral corals and growth.  Lately a lot of companies have been touting the values of amino acids in aquariums.  A friend also specified that for best uptake, make sure you dose the amino acids just prior to feeding, you may also notice an increase in polyp extension immediately following the dosing as the corals strive to take in the additives prior to eating.  The product claims to not interfere with skimmers which is a big plus over other options like Prodibio that typically cause your skimmer cup to overflow.  aquaLife Hyper Coral is available in two sizes at your local fish store.
