My alkalinity is at 5.04 dkh or 1.8 meq/l from 2 sources mine (hagen) and a local lfs (salifert). Is this level dangerous for the inhabitants. Should i be making a big change or can I raise it gradually?

I was thinking of baking soda. My math puts me at 32 g baked sodium bicarbonate will raise alk by 1 meq/l in a 90 gal tank. Does this sound right?

Other levels include calcium at 360 ppm. And Ph is at 8.0 morning and 8.2 at night.

Thanks,
