Calcium Chloride.

Baking soda adds bicarbonates.

Basically, if you have a low Kh, baking soda may be preferred since it raises Kh and calcium.
if your Kh is good, Calcium chloride, cuz it doesn't increase Kh.

How does baking soda (NaHCO3) raise calcium?

Baking soda does not raise calcium. At all.

I'm not sure what malkore's thinking is on this. He may have meant calcium carbonate (CaCO3).

Put some calcareous material in the filter. Just throw in some aragonite, oyster shells, limestone, etc. At the most it will cost you a few bucks if you decide to pursue the commercial route. Anything to raise the pH, basically.

Raising pH is NOT the same thing as raising calcium. Using baking soda or crushed coral raises carbonate hardness- KH, which works as a buffer for calcium use, (or CO2 use.)

You raise calcium by using a usable calcium product, like brewer's calcium chloride, or turbo calcium. (A reef product.)

You are right.

I think you meant CaCO3; which raises both Ca and CO3 (kH). The only downside is it takes long to dissolve.
