Kalkwasser + All For Reef + trace elements

[Dan Reef]

Hello!

I’m thinking in using kalkwasser to boost pH in combination with All for Reef.

Knowing that kalkwasser only adds alk and calcium, can I customize All for Reef to compensate other important elements?

Meaning increasing the amount of magnesium and K+/ A- added to carbo calcium.
Thanks

You can use kalkwasser to boost pH when using All-For-Reef. Kalkwasser is much better in boosting pH than in supplying calcium and alkalinity in which All-For-Reef ist much better.

If you want to add K+ and A- Elements for the kalkwasser added you just have to know that 100 ml of each K+ and A- Elements is added per mol of calcium. 1 mol of calcium is 74 gram of calcium hydroxide powder or 43.5 l/11.5 US-gallon of saturated kalkwasser.

Please don't add K+ and A- Elements to the kalkwasser directly but to the tank directly or to the All-For-Reef for automated dosing.

Hello Hans,

Can I add more K+/ A- to the All for Reef solution? Or do I need to dose separately?

What about the magnesium?

Thanks!

Also, do you see any drawbacks using the combination of kalkwasser + all for reef?

Hello Daniel,

I have not tested it yet but adding more K+ and A- Elements to the All-For-Reef solution should work. I am not sure about Bio-Magnesium but All-For-Reef is quite well supplied with magnesium. I am not sure whether it is necessary to add more magnesium at all. Maybe it is easier to wait for sinking magnesium concentrations first.

I see no drawback using the combination of kalkwasser and All-For-Reef, except maybe the normal "drawbacks" of kalkwasser.

Thank you Hans!

I was supposed to test that for you in my 100L tank. But my tank got ruined by Hurricane Ida in Louisiana 5 months ago. I was proposing adding more A- for what I observed, iodine was rapidly depleting. I was sending in ICP tests to establish a baseline.

Just restarted my tank. Upgraded to a 200 liter cube. I took my recipe I mixed up 5 month old “custom A4R recipe”, cut the concentration in half with 1000 mL of water and 143 grams of TM carbo-calcium.

DIY recipe still works perfectly — 20 mL brings up dKH by 0.6. it will be a while until I can get back to my 30 mL/100L A4R consumption.

Just add a skimbreez, it works without adding nothing to the tank

I am sorry to resurrect this thread, but I imagine that others might find it just like I did.

As far as I know, A and K elements should not be mixed in the same container. Could you confirm that mixing both when adding it to AFR solution would be okay?

Yes, I can confirm this. The reason is that the organic anions are effectlively separating the trace elements and prevent the unwanted reactions the may occur without them. This is the reason why both, K+ and A- Elements can be integrated in the All-For-Reef.
