Light for Clams

[andresont]

I am with Diana on that, clams and SPS do thrive and grow under PC lights and i even had one blue crocea on the bottom under VHO that was a year old.
Good example is when you scubadive you see thing so deep that you would not expect it would be there, more so you need a flashlight to see them.
IMO water movement and food goes before light. The more light you have the more water movement you need. MH is havily promoted by LFS to make $$$.
I have had MH on most of my tanks before and i like PC better.
JMHO.
