Icp test results

[Cnharrison]

Hi I'm new to marine and can't make sense on what I need to do with my results

Hi @Cnharrison .
You have some elevated parameters.
But more important by looking at your Sodium and Sulphur numbers your salinity is probably in 1.029/1.030.
Probably you are reading your salinity wrong.
What device you use?
You must correct it before going to trace elements analysis.
Correcting your salinity probably will correct your magnesium, potassium, etc numbers.

 

[Cnharrison]

A refarctometer

An icp test huh? Does this determine if you're a juggalo? HahHa

 

[teller]

I also use a refractometer.
How do you calibrate it?

I used calibration fluid

Any opinion on the results to help the OP?

So I guess do a few water changes with with lower salinity should sort it

Yes.
But more important is to know what value you read with your device.
Most probably there is an error in the result.
Or the calibration fluid is not OK or the device.

 

[Bapeluso]

Or you could take out about 5 to 7 gallons and replace with the same amount of fresh RO and test with a refractometer until it reads about 1.024 specific gravity. If you doubt your refractometers accuracy, take a sample to your local LFS and compare. They should be using one as well and compare results with both devices.

As an example. I follow my salt brand recomendation as number of grams of salt per liter of rodi water to achieve the salinity/SG i want.
I mixture and only after all dissolved i use the refractometer to test it.

 

[Bapeluso]

And as a general rule of thumb, that's about .5 cups salt to gallon of RO

 

[teller]

Your right.
But for people outside US cups and gallons are not that simple.
Some say a cup is 200 ml other say it is 250 ml. Some say a gallon is 4 liters others say it is 3.7l or even 3.8l.
So it is better to read your salt brand description.
Also different brands have different weights to target the same specific gravity/salinity.

 

[Cnharrison]

Yes.

Just used a different device now it's reading 1.030

Like @Bapeluso said you can change some saltwater to rodi freshwater to level it.

Will that sort out everything else

 

[Bapeluso]

Yes it probably will or at least be close. Most salts contain various minerals to help promote fish and coral health. That being said, removing some saltwater decrease the salinity as well as the other nutrients that you currently have an abundance of. The result should leave you approximately where you need to be. If I had to give an estimate, itd be about a buckets worth

So take out about 10l of water and replace with ro
