I'm doing some research on Ball Pythons. I would love to buy one (eventually) but for now I'm happy just researching them. I have an empty 75 gallon aquarium (with a terranium lid).
If I was to purchase an undertank heater, what size would you recommend for my aquarium? Zoomeds Repti-Therm line has heaters for various sizes (10-20 gallons, 30-40 gallons, 50-60 gallons, etc.) So how much of the tank underneath should be heated????

Also, can somebody PLEASE recommend a controller? (And be sure to provide the manufacturers name and a website link if possible) From what I read on this site, it's dangerous to just use the UTH as they can burn themselves if it shorts out.

Looking forward to your responses.

Cheers.
