I apologize in advance if this is not the right forum for this. Anyways I've had my light set up for maybe three weeks and I can already tell the difference. The cyano problem I was having before is no longer there. My zoas have great color and I've actually seen quite a few new heads popping up. Only after three weeks! Let's see what this baby does in three months! Excellent light and can't complain. Any of you guys with SB Reef Lights feel free to chime in. I'm sure many will appreciate it.
