Got it. Well 3 months into combining all the above(Mn,Ru,I,Se,Cr,Co,Fe,Zn,V,Mo,Ni) like I mentioned, we are seeing residual values in our monthly ICP's so my thought was that it was working. At least that was the measuring stick we have used so far. We don't do water changes either, so felt like we had a decent control in place to test that. I wonder if its possible that mixing up only 15 days at a time with a good amount of DI water is helping keep them from ppt or interacting, but that seems unlikely right? Thank you for any thoughts there @Randy Holmes-Farley . Here is an example of how we are calculating based on the ICP tests each month too.

The hexahydrate is 60% as potent as the anhydrous version, so with the same mass you used,

adding 1 mL (10.0 mg) to 1000 liters of water will give a final concentration of 10.0/1000 = 0.010 mg/L

So i have 0 chemistry background and trying to work backward to find out the concentration of what the stock solution would be.

using C1V1=C2V2 would be doing x=(0.01 mg/l * 1,000,000 ml)/(1ml) and coming up with a value of 10,000 mg/l or 10,000 ppm?

If you are trying to find the concentration of the 1 mL of fluid before dilution, yes.

Thank you, Randy, I appreciate the speedy reply. I am going through your list and trying to work backwards on a few so I am sure ill have another question in the future.

Vanadium is used by every organism, so it needed at some (undetermined) level, but bear in mind that they also recommend things with no known biological use, just for the sake of matching natural seawater levels of things.

Out of interest Randy, what elements from my icp should I ignore. I'm trying to avoid wasting time and energy on things that dont deserve it. Sorry if you have posted this before now !

Hey all, this thread is great. I went online and got the chemicals I need to supplement my reef after the icp test came back..

However the iron tablets I ordered came with the 4r red e124 dye, is this a deal-breaker, are they unsuitable now?

That is likely fine. A tiny bit of USP grade dye in a low dosed product is unlikely to be any issue.

#1 is 40% molybdenum by weight
#2 is 32.5% manganese by weight

#1 Dissolve 1 gram in 1000 mL RO/Di. Concentration is 400 mg/L or 0.4 mg/mL. Adding 1 mL per 100 gallons boosts molybdenum by 0.4 mg/378 L = 0.0011 mg/L (1.1 ug/L). Scale to what you want to dose (maybe 10 mL per 100 gallons)

#2 Dissolve 1 gram in 1000 mL RO/Di. Concentration is 325 mg/L or 0.325 mg/mL. Adding 1 mL per 100 gallons boosts molybdenum by 0.325 mg/378 L = 0.0009 mg/L (0.9 ug/L). Scale to what you want to dose (maybe 2 mL per 100 gallons)

These are dosed per gallon. Your iodine recipe is dosed per liter. I'm just double checking to make sure gallons is not a typo.
Also, I really appreciate your recipes for home brew dosing, you help make high power reefing affordable. Thank You!

Yes, I usually give dosing per gallon since most reefers in the US know their aquarium volumes by gallons, but chemistry math is often easier in liters for making dosing solutions.
