So I have a quick question.
I currently have a biocube 29gallon and I have added a 70w
Metal halide to it inbetween the two 36w CF
actinics. Although I have found that when I come to corals I have been drawn to the beauty of SPS corals mainly. I have a 70w
MH 10k ushio bulb right now and as far as colors I am pretty happy with it. I was wondering what everyones thoughts are on having just the 70w
MH.
I was thinking about replacing it with a 150w
MH or adding a second 70w
MH? Which would be better?
Also if I do add a 150w instead are the bulb holders from the 70w the same size? and would they work if I just changed the bulb and
ballast?
I know that both of these options will increase the heat and right now i have a few computer fans that I have built into the hood so to keep them in check and my tank has been staying relatively stable at 77 - 79 degrees. But with the added heat I may have to look into a chiller....I am hoping that is a last resort though.
