Cold Water Macro

[BigRed78]

Hello Everyone! I want to set up a ten gallon tank to house green crabs. They are a common fishing bait on the north east coast. It is an economical way to feed my mantis shrimp live food. I want to set up some sort of algae filtration but the tank will not be heated. Are there any tank subtitle macro algae species that can survive in water that is in the 60s. I'm also assuming I could not get away with mangroves. Thank you.

How about an ATS? It supposedly grows types of algaes to fit the condition given. Just an idea.
