I am setting up a Oceanic 30. Tank is dry waiting for a refugium from acrylicman. Lighting is in place - the Sunpod HQI MH 20" 150w with 12 lunars. The tank came with the 15 watt flourescent fixture. I would like to gut that fixture and retrofit it with an atinic only lamp, so that I have the option of viewing the reef with actinic only. The advantage of keeping the fixture is for aesthetics-it has the contrast cherry/black to match the stand. I am finding that most retros come with either a 50/50 or daylight bulb and so I would need to purchase another actinic bulb which increase cost. Any suggestions?
