supplements to coral and inverts

[hadena]

What are the best supplements, hince iodine, calcium and what all do they(inverts and corals) need. I know it depends on the species but a round about idea.

Calc and alk.

B-Ionic 2 part every day should keep everything good. Water changes should replace the rest of the essential elements.

Get a calcium reactor and once calibrated, dont have to worry about calcium and dKH as much.

I dose calcium and magnesium.
