This may be a silly question but is it ok use a tank that was previously a turtle tank for fish?
I have an opportunity to buy a 220 gallon tank that previously held turtle for a good price. Will the turtle bacteria harm the fish?

Welcome to MFK.

There are many ways to disinfect the tank if you are worried, but it should be fine!
 
I have seen many people keep with terrapins with fish , there would be no issue of turtle bacteria harming fish. However, as Hendre said, you might wanna disinfect the tank just in case.
 
Agree with Hendre Hendre but like to add inspect for leakage. After disinfecting aquarium fill aquarium and let sit for a day or two.

If it's a commercially-made aquarium, just clean it, test for leaks, and proceed as usual.

If it's a custom or DIY tank, consider the fact that it may have been built with a lower water level in mind if designed specifically for turtles...meaning that the glass thickness or other construction details are not intended to withstand the increased pressure of filling it up all the way. I had a plywood turtle tank for many years that was made from leftover scraps of lumber and glass from other projects. It was 6 x 3 feet x 3 feet tall, but the glass was only 1/4-inch, i.e. way too thin to withstand the pressure of water 3 feet deep. Filling that up all the way to use as an aquarium would have been a disaster.
 
Wash the tank with Dawn dish soap, fill to leak check. Aquascape, add water and fish. Be HAPPY.
