Calcium chloride

[Madonia]

Last I checked my alk is 8, but my calcium was 1380ish

can I add a calcium chloride additive to help raise?

how do I raise calcium levels only without affecting alk?

any recs on a good calcium chloride additive?

Are you sure about "1380"? That's super high, maybe you mean "380"?

There are lots of calcium supplements that can be used to raise calcium by itself and not alkalinity, I use the bulk stuff from BRS.

I use calcium chloride, works fine for me. Just dont raise the level too quickly and watch out because it causes a chemical reaction that generates heat. Nothing too serious but when I first did it I was caught off guard as the cup I was using started getting hotter over time.

Also, that seems like your Mg levels rather than Ca like Larry mentioned. Normal ratings should be in the 400's
