So you tried that mix and it precipitate?
Not yet. Was confirming everything with @Lou Ekus, as I didn't want to waste anything.

Or you could just do AWCs like previously discussed and not have to worry. Seems like you’re over complicating things.
Isn’t the water changes keeping up with the consumption of trace? If so it would be fairly easy to increase them somewhat. Like Randy said, this approach should be sufficient for a good while.I've already started that, but want to complete the approach for a complete Kalkwasser based dosing that includes trace.

If there’s not a drop adding more elements would be superfluous and potentially could lead to problems.
Right! That stands to reason. Thanks for the correction.No, water changes cannot maintain all trace elements at natural, unless the new water is far above NSW levels. That is because some deplete rapidly.
The additions may be adequate for the organisms, since we do not know how much of what is really required, but cannot maintain NSW levels of elements such as manganese.

There's really no such thing as a perfect "complete" trace element supplement since the demand for different trace elements vary a lot tank to tank. Since they come with foods, water changes, and other supplements (intended or not), and are used differently by different organisms, a one size fits all may not fit all.
I used only limewater (kalkwasser) for calcium and alkalinity, and while some trace elements that I never added as a supplement for in short supply (e.g., manganese), others were plentiful (e.g., zinc).
Ok. Here is the Kalkwasser based dosing regime that will provide equivalent All-for-Reef supplements.
1. Saturated Kalkwasser
2. 12g Bio-magnesium w/ 900ml of RODI and 100ml of K+
3. 900ml of RODI and 100ml of A-
For each ml of Kalkwasser dose .1ml of each of the Mag/K+ and A-.
@Lou Ekus @Randy Holmes-Farley Look right?
Recommended initial dosing for All-for-Reef is 5ml per 100L of tank and a maximum dosage of 20ml. This would translate to an initial 5ml each of Mag/K+ and A- and 50ml of saturated Kalkwasser and a maximum dosage of 20ml each of Mag/K+ and A- and 800ml of saturated Kalkwasser.
So for a 400L volume (my tank) recommended initial dosing would be 20ml of All-for-Reef. So for above, it would be 20ml each of Mag/K+and A- and 200ml saturated Kalk.
In my case since I'm monitoring Ph and Alk, I'm just limiting the raise in Alk by .25dKH per dosing...I'm dosing 4x a day. Per the reef calculator, it takes 900ml of Kalkwasser to have a .25dKH rise in my dKH.
Interestingly enough, the max dosage of All-for-Reef corresponds with a ~.25dKH increase. So I think I have everything lined up...
@Lou Ekus @Randy Holmes-Farley Thoughts on the overall approach?
I'm automating everything. So 3 dosing pumps instead of 4 is more efficient and cost effective. I am going ULM and don't want to do weekly testing...but will use occasional ICP testing in addition to my automated testing. I may end up getting a GHL Ion Director in the future. For now, I am looking for a good enough solution that can just use Alk measurements for major/minor/trace ion/element replenishment.If your have separate solution for K+ and A-, why not use them directly? You won't even have to use bio mg. Just add mg once a week or after testing.
Agreed, but it is at least in line with what TM recommends. So probably good enough for an approach.I find it humorous that K+ elements does not contain the element K+. lol
Other than that, it seems OK, though I do not know if all of those ingredients are necessary or if the amounts present are sufficient.
@Randy Holmes-Farley Per one of your other threads: "The immediate pH spike is about 0.6-0.7 pH units for each 1.4 dKH added instantly to seawater."
Is it safe to raise my Alk by .25 in 15 minutes? This is my current max dose that I am delivering 4x a day. By my calculation this increases PH by ~.12 per dose.
How fast is it safe to raise Alk in a reef tank? Instantly vs say 30 minutes.

Don't want to hijack the thread, but can you say more about this? Or point to an article or thread?I do not care for the organic additives additives in RC. I prefer, and only used, normal IO (except once many years before this article when I ordered RC by mistake. lol)

So I have some interesting results to start with.
Pre-dosing, I measured my Alk at 6.6dKH (GHL Director) and Ca at 463 (Hanna Checker).
After 2 doses of about 900ml each, my dKH has risen to 7.0 (as expected), and my pH has gotten the expected boost of about .14, but my Ca has jumped to 542ppm.
This rise in Ca makes no sense, as 1800ml of Kalkwasser should only raise up my Ca by a couple of ppm, so I'm guessing the Hanna checkers aren't as accurate as one would expect or human error. I'll rerun the test in the afternoon.
