I am converting from a 55 FOWLR to a 180 this weekend and plan to convert (slowly) to a reef system. Planning with the end in mind, I want a lighting setup for mostly, if not all LPS coral. I have read thru most of the old posts on lighting and have yet to see anything on how to deal with the heat generated by MH lighting (other than a chiller
). I am wavering between 6, 6' VHO's or 3 175 w MH w/ maybe 2 VHO actinic to supplement. I would like to avoid the expense of a chiller if at all possible, so I have considered using 3, 4-6" fans installed directly over the bulbs blowing up toward the ceiling to pull off the heat. I'm just not sure if the fans will do the trick with the MH s. I can wait for a while on the lights, I'm just trying to get some experienced feedback. Thanks in advance for your help.
