Homemade Manganese

[docscorals]

I read on here that some reefers mix their own manganese. I’ve been using Reef Moonshiners, but I am starting to go through a lot more because of the number of flower pot and Euphyllia I’m growing. Where do people get the dry mix to make it? I heard it is much more cost effective.

There are tons of recipes for these sorts of things in the DIY archive:

This is what I use:

Manganese gluconate is 12.4% manganese by weight.

Dissolve 1 gram of the solid material in 1 L of RO/DI. That solution contains 124 mg of manganese, so the concentration is 124 mg/L or 124 ug/mL.

Adding 1 mL to 100 L of tank water will boost aquarium manganese levels by 124 ug per 100 L or 1.24 ug/L.

Appreciate it Randy.

Is this the material you use? I found it on Amazon.

Yes. :)

i find my mix got oxidised rather quickly … but i store in semi transparent dropper bottles. You may wanna use light proof storage

What was the symptom?

Its light pink when freshly mix then the color faded over time with red/brownish residual gathers at the bottom

But just realised mine is manganese sulphate not gloconate

Thanks!

I had an ICP test (Trooic Marin) about 3 months ago which showed undetectable Manganese. I have a 43 net gallon reef and I’d like to dose the manganese gluconate diy recipe. How do I know how much to dose given that I can’t test for it? I also know manganese tends to be consumed quickly. I have a collection of LPS which includes a Goniapora. Any guidance would be greatly appreciated. Sharing the math used would be appreciated too so I can learn how to calculate on my own. Many thanks in advance!

One can only give educated guesses, but dosing the equivalent of full natural levels a couple of times a week is likely an OK plan in a reef tank with a reasonable amount of growing photosynthetic organisms.
