The fish /pet store on Towne Lake Pkwy is called Top Tails. It is in the Publix plaza. It has a small salt water section, but it's a lifesaver when you need water quick. They sell RO and already made up salt water. I don't have a RO machine of my own so I must buy it. I have had that " Oh my God! the sump is low and I out of RO water and it's 7pm feeling". They are only 5 min. away from me and open until 8 pm.
