ICP results

[reefandfish85]

I just got my ICP results back and some are really low like iodine

should I be dosing it ? What can I use to dose these trace elements?

Iodine as I understand it is quickly depleted in a reef. Not sure you should dose that iron not.


You phosphates seem really high tho.

Phosphate is only 0.096ppm I usually keep it at 0.1ppm

Those are mostly trace elements…replenish from brightwell has most of them, or Google trace elements in a reef tank

Might have to try Replenish.

Yup that seems correct based on phosphorus at 31ppb.
The ICP phosphate number I don’t get. Seems way out of whack. Maybe I just don’t read it right.
Iodine low, 0.03-0.06ppm better.
The trace metals I don’t worry about, but you can reduce their level with Metasorb or similar.
Check to ensure there not in your RODI made water for top off.

Oops! Sorry misread that!

My potassium came back at 600 which is little too high but I only dose Fusion 1 & 2 is there any other 2 part I can switch to that won't raise my potassium ?

Yes, but do you have a reason to think a two part raised it that much>? it would be seriously mismanufactured if it did (at constant salinity).

Which ICP company are you using? Not all are reliable, IMO. You might try a different one before acting on a potassium level that high.

I do not know if you will benefit from a trace element supplement, but it is a fine experiment. I personally did not find iodine dosing useful.

For an experiment, I'd trust Tropic Marin A and K over a Brightwell product as Brightwell seems to have some chemistry understanding limitations.

I used ICP-Analysis but then hear everyone a lot of people got different results through different companies so not sure which to trust then. I don’t don’t anything else besides fusion a+b unless my RODI is high in potassium which I am still waiting for results.
Which company would you recommend for ICP ?

I do not have a preferred ICP company, but trying any other one is a good idea, IMO. Or just ignore the potassium for now.

Seachem does have some issues with Reef Fusion (they claim it is for 1:1 dosing, but their label claim of potency doesn't seem to fit 1:1) so perhaps they have other design issues. Chemistry is not their strength, That said, I've never heard of anyone using it report elevated potassium.

What about doing experiment and send test to three different ICP companies with same day water sample and see what comes back .. how much do they differentiate from each other

That's been done, and is also definitely not the only reason I recommend getting a different test.

So I went and got Salifert Potasium test and after one drop of K-3 it turns light blue so I do have over 470ppm of potassium. now that test does not go over 470 , ICP came back with 600 so it might be accurate next thing I guess try to test fresh mix of my Salt water.

Edit: .. I tested my fresh saltwater mix @ 1.026 / 78.5F (RS Coral Pro) and it test right at 400ppm
