Natural Ca, KH and Mg??

[H-C6179]

Evening all,

Does Ca, Mg and KH naturally produce? I have a small 50L nano I've bought some supplements and test kit to start looking at corals. Gone to test Ca just out of curisoty and I've either done the test wrong OR its exactly where it needs to be?

I’m not exactly sure what are you trying to ask.

Alk, Ca and Mag do not spontaneously occur in your aquarium, they are part of the elements that come within your salt mix, so it is possible that if you don’t have any consumption they’ll be somewhere around the values stated on your salt package for that salinity level.
