Looking for Chiller for Cold Water Aquarium

[simpleton]

I live in San Diego and want to transform my tropical tank into a cold water tank with local inhabitants. The water temp here is between 55 and 65 degrees throughout the year. I need a chiller that can take an ambient temp of 80 degrees on average down to that colder temp. I have a 55gal tank.

I see a lot of threads that ask about chillers for hot climates looking to go to 78 degrees but, not many with my situation.

Any ideas as to what brand and what hp?

Thanks!
