Will precipitants occur if these compounds are combined together?

@Randy Holmes-Farley

Will precipitants occur by combining below compounds? I want to make a diluted rodi water solution so I can add via dosing pump.

I use Tropic marin part A and K. They do not cover my trace element requirements entirely.


Stock solution of the following.

Sodium Fluoride
Manganese(II) chloride tetrahydrate
Cobalt sulfate heptahydrate
Zinc Chloride
Vanadium pentoxide
Potassium chloride
Strontium chloride
Iron - ferrous gluconate
Sodium Molybdate


Ideally, would like to make a one gallon dilute solution containing all the above in proportional ratios that corresponds to my ICP test for that month to be administered via dosing pump over a 1 month time frame.

I’m dozing trace elements for a 400 gallon tank so the monthly requirements would not result in a very concentrated solution.

Trying to avoid 11 dosing heads for trace elements.

Thank you for the information.

I would separate Fe from the mix. Chem folks might have others they'd pull out as well.

@taricha, thanks.

@Randy Holmes-Farley your thoughts?

Trace element mixes are unusually complicated due to redox reactions, but I do not see an obvious problem. The vanadium pentoxide reacts with water and may generate heat.

Sr and F are not compatible

Good point. The solubility of strontium fluoride is about 1 g/L, so if the intent is to have concentrations higher than that, I'd leave out one or the other.

Thank you for the feedback.
