I'm curious about the role of lighting in coral growth. Is it the power or the color that makes a bigger difference? I've been running my tank with 325 watts of 6500K CFLs in a 90-gallon tank, and my candy cane coral seems to be growing at a slow but steady pace - it looks healthy, at least. On the ...

On the other hand, I have another colony that's brownish red with green centers, and they've only grown ...

Whoa, 100 heads in 18 months, Falcon9? You must be doing something right. I'm curious, what's your secret? I've been running a bit low on calcium, 330 ppm, so I just picked up some Seachem Reef Complete to bump it up to 400 ppm. Maybe that'll give my little guy the boost it needs. I'm thinking of ...

What's considered a healthy rate of growth, though - is it every three months, seven months, or even a year for a head to ...
