High Bismuth? Is this believable?

[andarre]

Just got my ATI ICP results back and according to them, everything is fine except for Iodine which is a little low, and Bismuth? Huh? Where would this be coming from? Salt mix? Magnet in pumps? Not sure what to do with this info or if I believe it.

Their reported value in my water is 6.97 µg/l which is 77 times higher than it should be. According to them, it should be at 0.09(!). FWIW, my RO water came back with 0 all the way down which is great.

Should I stick some Cuprisorb or some other media in the sump or not worry about it?

IMO, its no concern.

There's also nothing you can likely do about it. It looks and acts like calcium, strontium, and magnesium.

Exactly what I wanted to hear. Thank you sir!

Any idea what the culprit might be or is it something that can't really be pinned down to one sole source?

Spill any Pepto in the tank? LOL

 

[andarre]

Lol no, not that I know of.

Wouldn't surprise me with as much as they eat!

Many people see these low levels. likely an impurity in salt mixes and other supplements. An old salt study showed Bi well above your levels in one salt mix.

Realize it is very low, despite being higher than NSW.

Understood. Thank you again for the knowledge!
