Controls for KH, Ca, PO4, NO3, Mg tests.

I was looking for controls for KH, Ca, PO4, NO3, Mg tests. Are those available for purchasing? If so, where can I buy it?
Thank you.

There are nitrate reference solutions available I think from Hanna and probably others. You could check at Lab Depot and Hach. Googling "nitrate standard solution" comes up with a lot of hits.

The Salifert alkalinity tests come with an alkalinity reference, or did. I don't know of a cost-effective source for other standards. You can get a standardized saltwater solution, but it would be very pricey.

Fauna marin they have multi-reference solution, not really the best one but...

I am wondering if any reference solution would work for those tests or they need to be in saltwater for the test to work properly. I use Hanna checker for alkalinity and PO4 and Salifert for the others... Thank you.

The nitrate and alkalinity reference solutions should be fine either way.

I looked at the Fauna Marin. It should be okay if it's made carefully. It seems to be a standard salt water solution with some added nitrate, etc.

Right. I saw it and ordered from BRS. I will test and report back .
