I couldn't tell you.
I am mad at myself that I did the 720nm, because it is almost totally limiting.
Can screw on any other nanometer filters unless they're above 720.

Since the 720nm is blocking all the wavelengths shorter than 720nm, you won't see any different effect. For instance, if you were to try 590nm screwed onto the lens, then the lens would pass 590nm and longer to the IR filter in front of the sensor. And that filter would eliminate 590nm to 720nm leaving only wavelengths longer than 720nm.
But keep in mind that many or most IR filters do not have a sharp cutoff. It costs more money to make a filter with a sharp cutoff, and a sharp cutoff is not necessary to enjoy the IR effects.
