clean fish/turtle tank (Brooklyn/Queens)

Hi folks!
I’m helping my nephew set up a turtle tank and was wondering if anyone has an old aquarium, tank, filter, heater, or any accessories they’re not using anymore. I’m looking for something in the 5-10 gallon range, which should be perfect for a small but quickly growing turtle.

I’ll make sure to take good care of everything and give it a happy home. Thanks so much for any help—your kindness really means a lot to us!
