Checking for Levels in Turtle Tank, Algae accumulation outrageous!

I am unsure what I am suppose to do if my turtles tank (Red eared Slider) has too much PH or ammonia. Are there any other things I need to check for? I do see a lot of algae producing in the tank, any suggestions on how to combat that without harming Superman the turtle.
