The amino acid supplied in the review was for the food not to dose in your tank, at the levels you are dosing directly into your tank you will see only slow changes and will take about two weeks
Supernatant is the stuff you accidently dosed into your system and threw the food away.
Supernatant is the residue left from the paste after mixing, this can be mixed back in, if left overnight and you still have the residue mix it back in, this also is a sign you added too much minS
You got the directions from me

maybe should of left you with the ones on the bottle, quite simple to follow, mix then leave in fridge basically.
The paste should be dispersed into the tank by putting in front of a power head, alternatively you can target feed.
This is day one for you after the mixing error so impossible to see results so early on. It will take 10 days to 14 days to see results of continual use, then you really will see results if used as directed.
If used as directed no your nutrients will not go up, however if you continue to use the MinS on its own to dose you tank as well then please watch your nutrients. This second part was not part of the review but am happy for you to continue with dosing your tank with the MinS as you will see results in polyp extension an colouration if used correctly.
