ICP testing results.

[keatonmjenkins]

Hey all I’m needing some help reading and understanding these tests. I’ll post two results of my ICP test I just did. One is of my RO water and the other is my saltwater.

My RO test says I have very high copper in my RO water how do I lower that? Would that be a concern for my tank? Currently no coral are in the tank just fish but I’m having a lot of GHA in my tank.

Let me know what you think?

I would look at your DI resin. It does not look like it is affecting your tank yet though.

I would not assume that 3 ug/L in top off water is critically high, and since it is not present in the tank at detectable levels, I would not worry about it, but can you post the rest of the RO water report? it does not look like 0 ppm TDs water, and if not, it is best to replace the DI or put two in series.

Here is the rest of the RO report.

I’m just trying to figure out why I have a good amount of GHA when my parameters seem good. Tank is about 10 months old too.

I had just changed my DI resin out about a month ago.

What is the TDS that it is producing?

I think it’s between 1-3 tds

So there is no test of sodium or calcium or magnesium?

Yes there is.

Yes there is.

That’s tank water. I mean the ro/di water.

I guess not. I posted all the screenshots of the results for salt and RO
