Figuring out ICP

[xqtez]

I've lost a few coral colonies recently and am trying to figure out what is going on. Does anyone see anything wrong with these results.

First off, dKH is low IMHO. 8-12 is ideal for a reef tank. Yours is at 6.8, kinda low. I keep mine right around 9 or so.
Second, the Ca of 456.2 is fine if your dKH was up around 9 or so. The elevated Ca is possibly having a negative impact on your dKH.
That's all I got and probably not correct.
@Randy Holmes-Farley will set you straight.

Isn't the Mg a bit on the high side at >1500?

Meh.... Mine has always been that high or higher...1500-1600. Better higher than too low, to a point I'm sure.

Thanks for the help, ya I've been trying to raise the dkh slowly by adding buffer to the ato water. My calcium always seem to be right about the same but my dkh seems always low. I'm guessing that my salt must be high in Mag because I've never done anything to boost it.

I do not see clear problem except that many of the trace elements are undetectable and that means we do not really know how low they are.

You might try a commercial trace element supplement for a while and see if anything improves.

Do you have any trace element supplements that you would recommend?

Not really. I'd pick from a company you trust.
