I bought a goniopora frag last year and had trouble with it while in QT. It stayed shriveled up for 3 weeks. Not a great pic but you can see that it was not doing well.

I read on a thread here that a reefer was dosing 1ml of Triton manganese per 100 gallon a day. My QT is 10 gallon so I mixed 5ml of the manganese in 500ml of water and dosed 10ml of that solution per day.
That was the only thing I recall changing. I was very pleasantly surprised at how fast the goniopora improved. See the pics. The pics are over a 2 week period. I saw initial improvement within 1 day or 2.

Your post is dramatic and based on a single-factor change (that we know about). I started adding a DIY recipe of Mn a couple days ago and I think I have seen some improvement, but I need more time to be sure.
I ordered the first one.
Interested in this as well.I ordered the first one.
Do you have a general starting solution I can make? I have a 1 liter volumetric flask and I wanted to make a manganese supplement.
My tank is 260 gallons. Thank you!
Thanks @Randy for the receipt. I will order the second one then.Here's the calculation for the second one that Miami recommended (from another thread):
Let's suppose your target is 165 ng/L, which is a typical ocean value (it varies a lot). Triton uses a set point 10x higher.
100 gallons is 379 liters.
So a NSW value of 165 ng/L x 379 L = 62,535 ng (0.063 mg) in your tank.
From the stock recipe above:
Manganese(II) chloride tetrahydrate is 28% manganese by weight.
Here's a recipe:
Dissolve 1 gram (which contains 280 mg actual manganese) in 2.8 L fresh water. Manganese = 280 mg/2.8 L = 100 mg/l.
Thus you want 0.063 mg/100 mg/L = 0.00063 L or 0.6 mL added to the 100 gallon tank to match typical NSW levels.
IF you used manganese gluconate (about 12.4% manganese by weight) you would need to use about twice as much.
Thanks @Randy for the receipt. I will order the second one then.
Sorry for the ignorance, if i don't have a way to measure by weight (grams) for the formula which will be the equivalent let say in TSP, Cups, etc? Or is it better to get how the grams measurement?
Thanks in advance...
Perfect. Thanks @Randy Holmes-FarleyIt will be a rougher estimate of the amount to go by dry volume since the bulk density (the fluffiness) will vary. One I found claimed 1.15 g/mL, which would be 5.6 grams per level teaspoon.
Perfect. Thanks @Randy Holmes-Farley

I made it in a 1L solution!
I can’t wait to observe the effects to my Goniopora. I have one that’s been closed up for months and nothing I can do is making it better. I am so so so excited!!!

Here’s 2 of my Goniopora that seem to be more closed. I have other happy gonis, so I’m hoping this is the magic bullet!
The pink one and the big green one are both more retracted.![]()

I haven’t seen any benefit to be honest.Any updates here?
I use the one from reef moonshiners program.I am trying to find a manganese supplement for a Goniopora. The only ones I can find come with iron and in some cases, trace amounts of copper. I have fish and other critters in my tank, so copper is out and I'm concerned about iron. Are there any straight manganese supplements? What are people using for their Goni's?
