What is the proper nm for the acintic blue for soft corals and then for future reference what is it for stonies I have mostly all soft corals right now I had a real light blue light that wasn't cutting it n I order 160 nm blues to replace them are 160 nm what I want or do I need a lower nm that would put me more into the purple range or should I go with an even higher nm blue?
Need help with lights
