My tank dimensions are a bit different from most tanks I've seen. It is a Clarity Plus tank that is 60x18x16. This shallow tank allows me to keep higher light demanding corals without halides. Lighting is an Icecap 660 running 2 actinics and 2 50/50 bulbs. B-Ionic is the only additive that I use, and for salt I use Instant Ocean. I'm not exactly sure on the growth rate, and its probably been lower than it could have because I was gone for a while and didn't add Bionic regularly. That said, I would probably say its grown about half an inch in the past couple months.
