We'll have to do some more research on beginning a tide pool aquarium. I believe a chiller is quite expensive.
We do have a Maine State Aquarium in Boothbay, but we haven't been there yet.
The New England Aquarium is a large aquarium in Boston about 2 hrs. from us. New England Aquarium Home
They have a huge ocean tank, 3 floors tall and holds 200,000 gallons of saltwater. In this exibit they have a geen sea turtle, Kemp's ridley and loggerhead sea turtles, a nurse shark, barracuda, stingrays, moray eels and hundreds of reef fish. The aquarium is under construction right now though; it's suposed to be finished next July.
