Sharing ICP Results

[ReefHunter006]

Would like to hear the community’s opinions on my recent test. Particularly the heavy metals.

The tin can be from a lot of things. If you have a Red Sea tank with the green flex tube then that is your problem. This is a common problem. Search here on R2R for more options.

Also it looks like you dosing sodium bicarbonate and not changing your water. You might want to investigate that.

Those are my thoughts.

I am dosing 2 part esv b ionic with 15 gallon water changes every weekend on 60 gallons. Mind elaborating why you these results make you think I am not doing that?

CD isn’t an issue?

Your sodium is high.

Since the test doesn't show the chloride there could be balance between the sodium and chloride but be out of balance with the rest of your macros and trace.

Water changes aren't a sure fire solution to re-establish balance. I don't know how long you have been dosing and I don't know how faithful you have been to your water changes. I am just looking at your numbers.

CD isn’t an issue?

Probably. You may have an issue in your RO.

I would be curious to see a current picture of your tank.

From the level of stocking in your tank, your phosphate should be a LOT lower.

Likely from the SPS growing slowly or not growing at all.

Your coralline growth is really good.

The majority sps (except 3 pieces) are all relatively new frags from the last 2-3 months. They are all encrusting, I felt they were growing fairly fast. Phosphates this week have been between .03-.05 and I don’t like to keep it that low .05-.09 is typically my sweet spot though.
Here is an older sps at about 5 months now. Not the prettiest but I wanted to grow. Cheaper frag early on before I spent money on more expensive frags.

Here is a another of that same piece that a small nub broke off when I got it.

In my eyes everything is ok. Also Sn and phosphate are ok. Tin in this concentration is harmless. I just wonder, where the cadmium comes from. This is the only concentration I would think about.

Sodium: All major elements are more on the high side, so it seems balanced.

The corals look good too and the tiny frag is forming a basal disc, what more do you want?

I was a bit curious what others might see from the results that I am missing. Cadmium was my main concern that something is rusting.

I agree that everything looks mostly OK in the ICP test, but the salinity is a tad high, which is why sodium and sulfate (S) are high.

Certainly, making sure there is not a metal part in the water is a good plan. The tin is not high enough to be a concern relative to what otehrs see without apparent issue. I am not sure how much cadmium needs to be present to be problematic, but like all trace elements, its chemical form matters critically, and we cannot know that from ICP.

Appreciate it. Any idea if polyfiter or some resin filter like cuprisorb will remove cadmium.

Metasorb from TLF claims to bind it. Again, that will depend on the form.

I recommend not to take any measures by now. I would watch the cadmium and tin concentrations when doing a new ICP analysis in some month. If nothing changes or the concentrations even drop they might have come in with the salt or something else and you don't need to do anything.

The corals look good now and there are a million ways to change it for the worse. I have learned an idiom here at reef2reef: If it ain't broke, don't fix it!
