It is on Nolensville road. There prices are not as good as this sight, but if you do not want to spend at least $75, I would pay them a visit.
They are pretty knowledgable. You can also buy RO/DI top off water and RO/DI saltwater for $.99/gal. This is cheaper than I could do it if I bought the salt and mixed it myself. The SG of their purchased SW is 1.022.
They have beautiful corals, great looking fish and LR. The SW tanks are very clean, and not covered in algae, as I have seen in other LFS.
