Has anyone ever accomplished this? If i were a millionaire i would buy a pool and have corals in it and have the natural sunlight be the light sorce. Except you wouldnt be able to let rain get into it im sure.
In flordia people use pools as tanks and scuba with there fish. My cousin's friend has one. But it isnt outside its in a house/greenhouse in his backyard!
ive always thought of that. My uncle has a saltwater pool because its easier to maintain than chlorine and i told him that. That would be pretty cool though, costly, but you have your personal reef to snorkel in.
