Is this ammonia safe to use (cycling rock)

On another note, is there any way to calculate how much ammonia it would take to raise the water to 4ppm in a container with ~16.5g actual volume.

I'd look for ammonia without surfactants (soaps). The amount may be little enough to not be a problem, but I'd avoid it.

To calculate how much is needed, you'd need to know the concentration of ammonia in the cleaner. I don't see that in the pics.
