Help with water chemistry

[CNC_Lou]

So my SPS tank has been a huge headache. After 4 months of killing corals I sent in an ICP test and got some unusual results back. Anybody have any idea how to clear this up?

I also have a mixed that’s doing pretty well, So I don’t know where the gold is coming from.

Woot! You're rich...! Now if only you could figure out a way to extract it... How often are you performing water changes?

I’ve done a lot, I mean like once a week since I set it up.
4 months ago. And nothing was looking good after a week in the tank Which were relocated to my mixed a most made it back.
I kinda thought it came from my spray painting my rocks but I did the same with my mixed and it’s pretty happy. And it over a year and a half old.
Unless I dropped a piece of jewelry but I don’t go near the stuff. Gots me baffled

Not sure if cuprasorb will reduce those elements.

Ok, Think I might have found the source.
my grandson brought me a 30 lbs of salt from his high school from a failed reef set up, Not only that there was a 200 ml beaker in the salt, Assumed they use it to measure when mixing.
Who Knows what they used it for. Ughh
i knew I should have not used that salt.
ok, thanks anyway.

It looks like you have some chlorine in your RO water?? What is your TDS meter showing?

0

0

I'd personally get a second opinion on that... But how about you setup in general? What do your normal parameters look like on a daily and even weekly basis? Lets start there.

Looks like my meter is working by checking tap, If it’s really zero though IDK.
What bugs me is my mixed looks fine. This pic was take half way down ramp time and corals are only open half way. I didn’t know chlorine would show up on TDS?

gold wouldn't be a concern at 0.1ppb even if that measurement was real.
also...

LOL. That just really inspires confidence.

Chloride, not chlorine. It's no concern.

My mistake I read the graph incorrectly...

No problem. ICP cannot tell whether it is chlorine, bleach, chloride, an organic form like the antibiotic vancomycin, or something else that contains a chlorine atom.

That’s PPB
So it’s about .06 for PPM

I wouldn't be concerned at all based on the ICP results. The levels are likely at the limit of detection (LOD), well at least for the published standard curves from Triton. The limit of quantitation (LOQ) is typically 10-fold higher, so I don't believe any of the numbers for Co, Mn and Au.
