I am setting up a 360 and my heating and Air guys need to know what I want in my fish room for heating and cooling in the next hour. What would you suggest. I live in michigan and the room is 16' 6'. I don't know if I need a cool air return or heat runs in there or what. I have never had a tank is large in a closed space. Please help ASAP. Thanks
 
I would suggest both. But if you have central air conditioning, the same duct/vent should provide you both, no?

I would have both. Get them to put a cold air intake in the room also.

A vent to the outside of the house will also be very helpful to get rid of the humidity.
 
a return will help remove some humidity when your a/c is in cooling mode. alot of t-stats at refrigeration supply houses now include a humidistat or you can buy a module to add to a stat. it will run your a/c to remove moisture. I would have heat and cooling to help keep the tank temp more stable even if you are running heaters and a chiller. if the room is 16 6 square you have about 275 sq ft and in general without alot of windows or vaulted ceilings you might cool 500 sq ft per ton . normally a ton of air can be moved with approximately 400cfm so I would make sure they ran enough duct to give you around 300 cfm air to and from the room. tell them to put a manually adjusted damper in the duct not at the grill so if it's too much you can just turn it down a bit. if you turn it down at the grill/grills you will hear the air whistle. a 9 inch round duct is good for 300 cfm at normal operations or 2 7 inch ducts will do about the same . a 9x7 square will also do 300 cfm if they are going that route. we use round mostly in florida. an air duct calculator can be used if space is limited.
