Recent ICP abnormalities

[Ziggy17]

So my most recent ICP results are in. Everything looks quite well aside from a critically high Strontium, critically low zink in the sea water. Yet in my RO, critically high tin, zink, lithium, silicon.

I dose AFR, TM K+ and recently started TM A-

I find it odd to go from critically high in the RO to critically low in the DT, but none of the other trace are high in the DT.

Are you adding anything with strontium in it? If so, I’d stop. I’m not sure if it’s an issue. It should decline in its own with no additions.

I don’t think the ro/di is 0 ppm tds based on so much Si, unless it got in later. Do you think it was zero?

The only additives are the AFR and the TM K+ at the time of the test. So either the AFR or K+ had disproportionate Strontium in it. Otherwise I don’t know where it’s coming from. Unless it’s from frozen food (PE Mysis and Brine shrimp). There are magnets in the rockwork that I purchased from reefscape designs, but they are sealed in the Marco rock, so I doubt it’s that. Not even sure if strontium would bleed from a magnet even it was exposed.

The TDS meter reads zero, but they’re notoriously incorrect. I may have to move back to the silicon buster cartridge on the RODI. Sucks as they’re so expensive.

Why are you adding K+ and A- in addition to All For Reef?

K+ has strontium as does AFR.

 

[Ziggy17]

my last ICP had certain low trace elements, even with dosing AFR. So the K+ is to replenish the low iron, maganese, zink. The A- is recent and is not applicable to this Icp test, but dosing for the iodine, bromine and fluorine that were also low on the previous ICp.

 

[Randy Holmes-Farley]

Agreed, id drop the A and K for now, or at least the K.

Sucks that it’s only causing one to increase disproportionate to the others that I was replenishing with K+

I suppose it’s a good argument for moonshiners.

 

[Randy Holmes-Farley]

It’s possible there is some other explanation, but it’s a start.

I'm not sure it is an argument but as RHF noted above it is a place to start (pausing the additional dosing products from TM). Depending on what is low and by how much you could maybe just buy single products and adjust one time. Retest 3 months later and see how it goes if it is a major concern.

I recall a couple of my ICP tests reporting that Fluorine and Vanadium are low so I purchased those and added their recommended amount. I didn't noticed anything in the display change but the next ICP test the recommendation was corrected and no more /shrug

Thanks for the input gentlemen.

Individual dosing is Likely what I will have to do. I’d like to get Lou’s take on the fact that all of the elements aren’t rising in a linear way, just one in particular. Perhaps SPS don’t uptake Strontium the same way that LPS or softies do? My tank is SPS dominant aside from a large and small hammer and a medium size Goni. I had torches but they don’t seem to enjoy my tank so I’m not replacing any.

One issue with ANY combo supplement is that it can only guess at the relative amounts of coral skeleton incorporations (e.g., strontium, magnesium, barium and calcium) vs the relative amounts of elements mostly going into tissues (e.g., manganese and iron) such as hard and soft corals and macroalgae. Those relative amounts will vary tank to tank.

In a tank with high macroalgae and soft coral growth, if you used one of these products to maintain elements they need, you are likely to find the skeletal elements rising too much.

My Sincerest condolences to his family. That’s sad news.
