I have not made a solution yet, thus asking for the math check. I have a scale that can do grams but not mg, which was why I was asking about a volume measurement.

Where did that rule of thumb come from? By that it looks like 1 tsp is equal to about 2.5 to 5.0 grams, which if dosed to my 450g tank should bring my nitrates up by 1.0-2.0. Is that correct?

I dont mind it being a little off, I can adjust the mix and dosing later. Im just trying to get in the ballpark to start and not accidentally dose my nitrates up to 30 in one shot.
