Now that I've discovered this:

Saltwater Multi Reference Solution

The only reference solution based on a saltwater matrix that includes 8 of the most popular parameters for saltwater aquariums in a single solution. Fauna Marin’s Multi-Reference Solution is used to check your home water test kits for accuracy. Using your water test kits at home, you can measure...

Quote: Each bottle is manufactured in the Fauna Marin Seawater Research Laboratory and tested using an ICP-AES machine with each batch to ensure reliable and accurate results.

Why wouldn't you use this ICP tested/verified solution to finely calibrate your tests results? Validify your test results?

How is this any different than having a certified exactly 10oz weight to calibrate/test/validify your small digital scale.

At $20 for 100ml of deadon accurate #s, even if you use 10ml to calibrate your test results, it's $2 a calibration.

Beats doing a $50 ICP just to get basic test results like no3, po4, calc, mag, alk.

This solution would give you very accurate validified #s thus giving you the accuracy of an ICP test by association

I do have this solution and I must say it is very accurate.
My testings with salifert are on point with that they state.

So I can really confirm this solution is a good way to calibrate; it is very precise.
