I just went to a new LFS in Roswell,Ga . Southern Aquatics on Holcomb Bridge Rd .Very friendly and helpful staff . I asked about aquarium safe silicone lube which they didn't have ,but Dana looked up a dive shop online for me . It was just a few miles down the road on Holcomb Bridge , Sea Ventures , and they had 100% food grade silicone lube for a good price . I recommend both of these shops for their customer oriented way of doing business which unfortunately is getting rare these days .
