I am a fairly new reefer, I have 6' long 24" deep 135 oceanic with live rock and soft corals afew sps . Running now over a year. I have a 80 gallon sump with refugium as well as pro skimmer, chiller, calcium reactor, my lighting is a hamilton 6' 3-250 metal h with 2-6' vho's. My corals since about 4 months new have not grown or flourished like many of my friends tanks. I have asked my reatail guy what I am doing wrong he seems to keep stringing me along to just keep buying more stuff. I have tried 10k bulbs,14k bulbs and 20k bulbs. I have asked how high to set my fixture off the tank he said as close as possible but somehow it just seems too close... I also use ro/di water and all my tests are mint???? What am I doing wrong.... I give up
