Your hypothetical is pretty close to my tank except I do water changes.

I'm going to vote for D; my understanding is that kalkwasser is a balanced supplement regarding calcium and alkalinity, and that corals take them up in equal amounts as well so I would expect the calcium to remain stable as the alkalinity is stable. Since there is no magnesium replacement and you can get some magnesium precipitation, that should slowly decline. You aren't going to get hydroxide buildup as it converts to bicarbonate or carbonate.

d, cuz it's what I do.
Oh, and I also do water changes.

You shoud read about one of the reasons why Randy prefered basic Instant Ocean for his salt.

What's the answer @Randy Holmes-Farley

Patience.

I would also like to see this because I use only Kalk and IO. Seems to be doing really well.

Ah well, many of the threads that come up asking for "BEST" and "SALT" and such may have it in there. Along with one of his articles.

I'm sure I have seen it a few times in that case, doesn't however ring a bell.

I think you're right

Come on Randy !

 

[FirstContact]

Going with D.

Well from what ive put together over a while, is if your dosing kalk only. Your calcium usually rises because the incorporation of mag in the skeleton lol

And other uses of carbonates beyond calcification that don't involve Ca. Randy makes all of this quite clear in his well written articles.

 

[Keiffer the reefer]

A & D for sure. Curious about the E/F thing. Is hydroxide alkalinity significant?
