I'm not sure how much you want to raise them.

I wouldn't add anything for alkalinity.

I do boost the magnesium in IO without measuring. I add enough to boost it by ~150 ppm, which offsets loses in the tank, where I never add any. I don't add any calcium to it, but if you do, the calculator below will tell you how much (also for magnesium):
