These bulbs probably do promote coral growth, as do T5 lighting, but you have to have enough of them to get the necessary light for your critters. One bulb just isn't going to cut it, I have 2 x 150w Metal Halides over mine with 110w of T5 Actinics and even that isn't enough for some. I'd go for either a 2 x 150w metal halide fixture or a 6 bulb t5. If you stay with the bulbs that you have, you'll need to get about 6 of them, and even then that will limit what you can keep. Metal Halides fixtures are pretty cheap on ebay, why not try to get 1 250w fixture and buy a 10-14k bulb to go in there.
Here is a 250w lighting fixture on ebay:
