Thanks Steve (I am hoping that's your name
).
I, once more, got confused about what to do with my light, a phobia that I always suffer
With my 62W T5HO, I am getting coral growth and I won't complain that I am lacking light, but its just that, I know that the corals can do better. I have a montipora cap around 1/3 up the tank and its growing nicely. But I feel like the tank can use better lighting. I can easily grab the same fixture for like $50 but the problem is the upkeep of T5HO bulbs.
I would definitely do metal halide if I can mount them without drilling but halides get me worried about heating up the water. Plus with the small rectangular pedants, I think I need two which, again, would add up the upkeep.
That's why I wanted to go with LED. But looks like I won't be able to because most of the led DIY is hanging type and getting 30" heat sink would be expensive for multiple rows. But I have found 30" heat sink that can fit single row LEDs for $20.
