I have to say I don't use any chemicals to control algae. That said, if it says it's safe for plants and fish, I'd assume it would be OK for turtles. If you don't have a lot of algae in the tank, and it's just on the edges of the basking area, etc., I'd just leave it and give the tank a more natural look.
