Wow, some bad Triton results...

[Larry L]

I just got back my Triton results, and everything was nicely in the green... except for four readings which are off:

For comparison since my first test results 7 months ago:

• AL 125 -> 132 (probably my MarinePure blocks)
• Li 362 -> 373 (not much change, but why so high?)
• Cr 0 -> 4.89 (what the heck happened there?)
• Si 229 -> 762 (what the heck happened there?)

What could have caused my Cr and Si to jump like that, and how do I fix them?

Is the elevated Li high enough to worry about, and if so, how do I fix it?


Thanks!
Larry

Lithium - probaly your saltmix no biggy IMO. Many are much higher

Si - Look to replace your DI and if you have recently there may be channeling. And if you get your water from your LFS tell them to replace their DI. Sponges will like it and diatoms

I have lithium an order of magnitude higher than yours. Relax about lithium. Same for silicon. I've seen many tanks with aluminum levels in the 50-150 range. Chromium, on the other hand, is almost never detected. That's the one to focus on.

That's the general idea...

Any metal parts in the water? Hose clamps, etc?

Thanks for the comments, everyone, I appreciate the help.

I haven't found anything yet, but still looking... In the mean time I figured I'd throw in some Metasorb, but when I read the label it does not mention that it removes Chromium. Does anyone know of anything that *does* remove Chromium?

I have been *really* struggling to keep any LPS or SPS alive in my tank - everything seems to dwindle and then bleach and die after a few weeks to a few months (but not my clams, softies, snails, or serpent stars - the are all doing fine). Considering that everything else in my Triton test checks out, is it a safe assumption that the high Chromium might be toxic enough to kill stuff off?


Thanks!

I do not know. I've not see data for most of the metal binders, and it would be highly suspect anyway since most of the trace metals have multiple forms in a reef tank and many are highly bound to organics, impacting what else may bind them and to what extent.
