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.

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

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
