Best calcium supplement

[cnjcpb]

What is the best calcium supplement to dose? I can’t seem to keep my calcium above 380. Thanks!

There are many ways to supply calcium, and the best ones are tied to alk dosing.

Are you supplementing alk now?

I am dosing 10 drops of All for reef. My alk was low at 7. It’s up to 8 now.

Have you used that kit on some new salt water? It may just be low in calcium, or the kit is off. AFR provides enough calcium to offset consumption when added to maintain alk.

If the salt mix is low, just add calcium chloride to it. DIY, or quality hobby brand.
