I read in the coral magasine (anorexic reef article) that an aquarium that is less than a year does not have enough zooplankton to give a good sps growth and that after an aquarium as matured and is one year or older than the established population of microscopic fauna will help them grow much faster. I too have slow growth in my 9 months old aquarium so feeding help but a mature tank does best with natural plankton.

Reefroid, coral frenzy and zeovit amino acid can help with their growht speed as well.

Also try running carbon for a while as this might be due to coral releasing toxine in the water and preventing other coral to grow. Maybe do a copper test to see? and test for stray current, you never know. Mine as starting to grow but growing sps is much dependant on each coral and some specie grow faster than others. Most of the lps must be fed, especialy like duncan, alveopora etc... I had my ricordea receiding and I had no idea why until I accidently dropped food on one and it ate it all. It just took so long that I had never realised that ricordeas eat as well. I need to shut off my pumps for 30 minutes and let them eat. Now they are growing big again.
