Icp results

[Charlie’s Frags]

What do you all think?
Bromine and iodine are low but sulfur and arsenic are high. Anyone know what could be causing these to be high?

 

[Charlie’s Frags]

Sulfur mystery solved. I must be adding a little too much prime

 

[Gareth elliott]

Sulfur is not that much higher than nsw, personally would do nothing with that number.
Also would do nothing with the bromine number either. The arsenic is pretty elevated, about 4 times higher than the epa allows in drinking water. Any electrical components that could leach to water like a heater that contains any silicone chips? Or perhaps contains a battery?

 

[Charlie’s Frags]

Not that I know of. I should send my r/o water in to see if it’s from the city or something in my tank. My heater is the flat looking one made by hydor

What do you mean by silicone chips?

Sooo
I have 3 icp test
July 2018 arsenic measured 0.013
Nov 2018 arsenic measured 0.050
Jan 2019 arsenic measured 0.042

The only thing that changed between July and Nov was a new bucket of tropic Marin pro

I’m going to make a fresh batch and send off a new sample

Sources of arsenic for a reef tank computer chips, batteries and spayed pesticides.

 

[Charlie’s Frags]

What pieces of equipment in my sump would have batteries or computer chips? Could frag plugs that were dipped in bayer leech arsenic?

 

[Gareth elliott]

imidacloprid is main ingredient in bayer. A nicotinoid(probably spelled wrong lol) does not contain arsenic. Its being discontinued in some areas has to do with its toxicity to bees.

Any equipment could potentially have a semiconductor.

Also this could be source water or salt added. Ati will test your rodi as part of its test. Also could verify if perhaps this result is incorrect and their calibration is off on this element at icpanalysis.com just a thought before taking the tank apart.

 

[Charlie’s Frags]

Sounds like a good plan. Thanks for your help

I agree that it is probably the salt or the water source that brings in the arsenic. It will build up if there is even a trace in either. What salt do you use?

 

[Charlie’s Frags]

Tropic Marin pro

 

[Charlie’s Frags]

I just sent another test for my r/o and another test from a freshly made Tm pro

 

[Charlie’s Frags]

Received my results from a r/0 sample and a freshly made unused sample with the tropic Marin pro.

So i have not read the entire study, but if they did not calibrate correctly for salt water this test might not be valid.
