I have 2 full spectrum d120's about 16" over a 4' 150g. I am running the whites on 20 and the blues on 25 and the only corals I can keep are some mushrooms and zoas. Even corals like frogspawn melt in about a months time. All perameters are perfect. I have heard of people having alot of succes with these but I can not seem to get the right combo. Does anyone have any advice for me besides "go get other lights?"
