I just went through this with mr x on one of my threads yesterday. he said that as long as the Par is there it doesnt matter the 20k or 14k as far as coral growth. Because I don't even have actinic supplement with my setup I was really concerned.
Not sure which of my threads its in might eb the 20g rimlees one. But he went great lengths to explain it all to me
How can I find out the par of the odyssea bulbs? I googled it and can't find it
