I tried a couple of stores in Boca area. I like Barrier Reef, but it's always a madhouse and I find myself waiting a while to get help. However, I always get my water there now as I've had problems at other places. Last year after the hurricanes, I couldn't get any from them. They told me that they get their water out of Biscayne Bay in Miami, and they haven't been getting any because the water was so stirred up from the storms. That to me is a good thing. I assume it's true, but I never had problems with their water either way.
I've been wanting to try this site to order fish, as they are close to us (Ft. Pierce). However, I work an hour from home, so the fish would have to stay with me all day at work. haven't been brave enough to try it.
