Arsenic?

[marlinmon]

Just had a high arsenic reading as well from ICP-Analysis. 0.055. Have been struggling with acropora for some time and wondering could this be the cause? I have no idea where this could be coming from.

Can't imagine it came from your RO source. Drinking water standards are <0.01 ppm, I believe. Maybe leaching off a piece of equipment? Or analysis mishap?

Anyone get additional information on this? I got back some ICP test (non-Triton) results recently that showed high levels also. Last time I did an ICP test (a Triton test), my level was zero. However, since that time, I've changed salts from Red Sea Pro to Fritz's Pro. I dose 2 part - two little fishes. I've seen articles online that suggest certain salt mixes can have high levels of arsenic depending on the grade of additives used.

I'm using Fritz too but my sps look great so I'm baffled unless ICP is off

Does high arsenic levels mean sps will struggle and (if so) at what levels? My sps are generally fine also. It seems strange that it would be an ICP issue, since I wasn't using Triton but others were.

I just got my icp test back and it is showing .031ppm arsenic. Last three tests showed 0.

The only change I’ve made is feeding Masstick.
