RODI and saltwater

[Charris]

For my peeps in the Murfreesboro area, is there a local store that sells RODI and saltwater? I will eventually mix my own saltwater but starting out I will most likely just purchase.
Thanks!

Oceanside in Mt Juliet probably sells it or Aquatic Critter in Nashville definitely sells it.

Emerald Bay in old Hickory usually has a great deal on it.
