Nitrogen

I'm trying to bring up No3 to 5ppm. How much Neo Nitro is safe to add in a day? I've been adding 40ml daily for a week and still at 3ppm. Phosphate has been added as well trying to stay at 0.02 but some tests were as high as 0.21. Today phosphate is 0.03.

40ml should bring my 120 gallon tank up 1ppm.

Any thoughts? Looks like zoas are melting away.
