Answer:
Used to
Explanation:
"Too" means as well or excessively, so that does not make sense if you were to say "After I moved to Miami I had to get used too (as well/excessively) the weather."
Use to is in present tense, but if you will notice that whoever wrote the sentence used "After I movED", which shows its in past tense, and you cannot mix up past and present tense in the same sentence like that.
Hope this helps and isn't TOO confusing ! :)
