DIY molybdenum

[pigmo]

hi just a quick post, my brother made a batch of Mo supplement equal in concentration to ATI's supplement. the formula is on the yellow post it



@Rickyrooz you mentioned your diy formula caused issues, was your formula different?

 

[JimWelsh]

FYI, that works out to 0.2 g/L of Mo, not 2 g/L: 0.7595 g / 1.5 L * 0.395 = 0.2 g/L. EDIT: The 200ug/mL part is correct, though.

 

[pigmo]

yes the post it should read .2 g/l, thanks @JimWelsh

if you believe the marketing... maybe ask @Randy Holmes-Farley

@Rickyrooz we dosed the above mix 2x so far without issue

All photosynthetic organisms use it, and even a small amount of algae can deplete the tank of it very rapidly.

Thanks! Is there a good rule of thumb (i.e. add X ppm every Y days) that would be recommended to add Mo for a fully stocked mixed reef?

I’m not really doing regular ICP tests.

I was mistakenly thinking of manganese, not molybdenum. Sorry. Manganese depletes faster. I don't know of a simple dosing scheme that is always desirable for molybdenum.

Here's my take on it when I measured mine:

My Triton Testing Results: By Randy Holmes-Farley - REEFEDITION

Recently, Triton GmbH in Germany has initiated a method of testing many ions at once for a single price. In the US, that service is coordinated by Unique Corals. For $49 they will send you a couple of tubes to collect a tank water sample, and a prepaid mailer to send the sample back to them...

Molybdenum (Mo). Molybdenum is low, and if that is true, it’s an interesting and potentially important result. I don’t typically add any trace elements. I may consider adding some molybdenum as it is biologically important.

The last time I did an ICP test, the Mo result was 0.002 ppm, so similar to the result you got.

But interestingly, the Triton setpoint of 0.012 ppm is quite different from the coralvue ICP setpoint of 0.0015 ppm, which is supposed to be the level in Fiji. Not sure which is more appropriate.
