I'm planning to set up a reef tank and wondered what lighting parameters would give me the optimum light. Tank is 72x24x24 and I considered the Coralife 72 3x250 or 3x150 .I am not into sps and will most likely stock zoos,leathers,mrooms,lps,rics,yumas you get the idea.The only negative I see with the Coralife fixture is the colour of the mh,I believe they are 10k but seem very yellow to me. Thanks in advance for your replies and suggestions
