The hobby ICP test industry are not using validated methods, which means they cannot tell you how accurate and precise their results are. That being said, the ICP test result is not a list of random numbers either. Element concentrations above 1 ppm are likely to be measured well. Element concentrations below 1 ppm, the one we call trace elements, are not going to measured as accurately. ICP-MS is more sensitive than ICP-OES, but not necessarily more accurate. It will be more likely true that a very low concentration element is detected with ICP-MS than with ICP-OES. ICP Analysis.com seems to do less well than other vendors in measuring element concentrations.
Currently my tank is struggling everything was good for a while I was having algae issues and my zoas didn’t look as good some days but after struggling to get my nutrients down I finally got phosphates to stay below .06 settling around .04 and nitrates around 5 first my zoas all started closing and melting away although a couple of my colony are doing well still just no longer growing. Then all my hammers started having the tissue band dissolve then bailing out my torches are all still fine and some of my zoas and shrooms are fine but lots of my zoas shrooms have bleached and died a couple of my acros are turning super dark and one died but all of my hammers are bailing out/ dissolving away. I think it might be nutrients too low but I brought them back up to phosphates .15 and nitrates 20 but only difference I’ve seen is some zoas ar opening up better now but my hammers are continuing to die. I am going to get an ice test because I don’t want to keep losing coral do you think I need the more accurate ms one in this situation or just the oes since I’m looking for major issues. Also if it was low nutrients that caused this would my hammers continue to die after bringing them back up maybe they were too far gone or something. I feel like one or two of my torches are starting to show signs of deteriorating flesh bands but nothing like my hammers. Hammers started dying weeks ago phosphate has been back up for over a week.
I did an ICP test with ATI and my Tin, aluminum and barium came back high and I will like to confirm with another ICP company, Do you still reccomend Oceamo?
I tried to order an oceamo but apparently they don't ship to USA. It not in the list of their shipping countries.It’s either or.
MS has much lower detection limits/ sensitivity for several elements while OES will only detect certain elements once they’re overdosed or not at all.
@TX_REEF
Thanks for this info. Pretty helpful. Now let say Tin is coming from tubing. Now what aluminum and barium is coming from.Acrylic won’t leach. The Red Sea dosing tubing will probably be your Tin source.
Aluminum is usually from biomedia.
I don't have biomedia, just have marco rocks in my sump, reef mat, skimmer, carbon reactor, acrylic stand, aquatop titanium heater, jebao powerhead, ecotech vortex m2, AI axis pump, sicce pump, auto top off it was aquatop, just change it to the redsea.Aluminum is usually from biomedia.
These bricks below are clean. Not sure what you have currently if any at all.
What are you dosing btw?
