Hi, I believe your LFS should have clarified and said the T8s are good for soft Corals, which they are. Now, one caveat to that is that your tank is deep so some softies may need to be moved up in the tank but T8s are fine. You need to purchase a Magnesium test kit separately. I use Salifert but sometimes they are hard to get (sell out a lot). When purchasing things on line my shopping comparison choices consist of; Marine Depot, That Fish Place, North Coast Pets and Drs. Foster and Smith. Like we discussed earlier about how young the tank is, your lights are fine, the Coral is in there, so just relax and enjoy the hobby!!
