I am from Palm Harbor and I know a few good places in the area. There is Exotic Aquatics on the the corner of Main st. and CR1 in Duneiden. Thats where I get my RO water and most of my livestock. Then there is this place in tarpon on the corner of Tarpon Ave and US 19 that sells saltwater. The guy there knows very little and usually sells things real cheap cause he doesn't know any better. Then there is Marine Depot on Hilsborough a little East of Dale Maybry, big store with lots of stuff. Anything else.....
