Just replaced my bulbs a couple weeks ago and picked up a coral plus to try it out. I really like the bulb. I've got a 4 bulb ati sun power; and before I used 2 blue+, a purple plus, and ge 65k daylight bulb. This gave a very white look which I was ok with, but I wanted a little bluer. I tried the aqua blue special and it was too blue for my liking. The coral plus for me is the perfect combination. Bluer than with a 65k, and not as blue as the aqua blue. The colors in the corals pop and I really like the effect. As for growth I can't really say because I've only had the bulb for a couple weeks.
