How fast is fast in growth for SPS?

I'm not so sure there is such a thing as "normal" :-) I have frags that have grown into colonies pretty "quick" (1-4 months), and I have frags that have done nothing in 4 months!

Here's a tri-colour I ordered online back in June of this year. It was a 1 branch 1" frag.



Today it is a nice little mini colony.


Here's a 1.5" christmas millepora frag I got back in August 2009. This picture was taken August 29th.


Today (just 8 weeks (ish) ), it is a nice colony.



All of my bird's nest frags tend to be quick growers like this too but I also have a few frags I got back in late spring (june ish) that haven't grown a millimeter :-)

I find it's really species dependant. My old tank had Marie style growth, one piece put on about 4 inches on each branch in 2 months. Other pieces I had grew an inch in 6 months.
Besides lighting, make sure you have strong flow (although not direct flow on coral), and great water quality. This means proper alk, Ca and some people measure Mg as well. Mg has just been a recent concern in the last few years, so I couldn't tell you what my levels were when I had my "steroid tank". I do know I had to throw frags in the garden because I couldn't give enough away.

WOW.....I must be doing something wrong, I'm only getting a fraction of the growth that you guys are getting.
