There is quite big difference between the LFS tests PO4 from 1.2 to 0.4, Calcium from 345 to 250, that is strange looks like there is precipitation, are you using tap water for water changes?

It said it is for plant’s tank

Plant tank additives are generally fine for dosing in reef tanks but only if all ingredients are properly listed (which rarely happens), because quite often freshwater additives contain some other ingredients like phosphates, nitrates, iron, potassium and could cause problems in a saltwater tank.

What do you mean by that

Are you asking me what I mean by Seachem not providing purity info?

It means they do not say anything about how pure it is, and you are trusting them to make such decisions for you. I do not trust Seachem to make chemistry decisions for me.

If you buy a food grade or reagent grade product then it carries a purity guarantee that comes from being food grade (or whatever grade it is).

Here's an example:

Have you tried measuring alkalinity in your RO/DI water?
