Hi Steve,
A 240, what a great gift!
I keep my tanks at 80-82f; as Doug said, a bit higher or lower depends on what corals you keep.
For your Aiptasia, please see this site:

I would recommend a more up-to-date book(s). The Conscientious Marine Aquarist, by
Robert Fenner and/or Natural Reef Aquariums, by
John Tullock are good ones (about $25 apiece online). I would suggest reading one/both of these before getting any further along with the project. The Reef Aquarium, Vols I & II, by Sprung & Delbeek, is an excellent comprehensive reference. Another encyclopedic choice would be Modern Coral Reef Aquariums, Vols I & II, by Fossa & Nielsen. For Corals, A Practical Guide to Corals, by Puterbaugh & Borneman, or the more detailed Aquarium Corals, by Eric Borneman, are good to have. Having a current reference library is an essential part of this hobby.
Please tell us more about the tank: parameters; test kits; skimmer; pumps; sump; substrate; rock; etc.
Also, where are you located? There are bound to be some TRT members familiar with good local resources.
Glad to have you aboard!
Dick
