Dosing with Aquavitro

Hi,

Apologies for such a basic question. I’m using Aquavitro Synthesis and trying to calculate an appropriate dose on Rotala Butterfly and it returns values for N and NO3.

If chasing a specific NO3 number i.e. 30 ppm do I:
A. Solve for NO3 and ignore the N component
B. Halve the NO3 target and accept the N value.

It makes a big difference to the amount of ferts used.

I understand that N converts to NO3 at 4.43. In the 30ppm example it would be
15 ppm NO3 and 3.41 ppm N (according to Rotala Butterfly) which equates to roughly 15ppm NO3.

Similar issues occur in
activate for phosphorus and phosphate; and in
seachems potassium between potassium and potassium oxide.

Any advice is much appreciated.
Martin

Here's a quote from Seachems website: "Use 5 mL per 680 L (180 US gallons) twice a week (or as needed). This dose increases total nitrogen by 0.24 mg/L. This is the same amount of nitrogen that would be present if all nitrogen were present in the nitrate form at 1 mg/L. "

So 5ml/180g increases N by what would be 1 ppm expressed as NO3. It might be easier to calculate based on that.
