How does fish feeding translate into nutrients? N and P specifically!

I do know some foods have the benefits of introducing trace elements into the tank, but I am wondering what you may do to keep your nutrient imports (N and P) as consistent as possible on a daily/weekly basis.

Do you use an auto feeder?

Do you use pre-portioned foods like frozen cubes?

Are you taking nutritional analysis and converting the weight into PPM to calculate the exact amount added per feed?

Or do you just eye-ball it and feed more when readings are low, feed more when readings are less?

I mostly feed TDO 2x/day and continue to bottom out my nutrients. So I bought frozen but am afraid of excess DOC and bacteria infections from overfeeding my nano. So I feed that about 1-2x a week and broadcast. I do have benepets to feed corals but have not done it consistently. Lastly, I started dosing ammonia bicarbonate to assist with nitrates. Currently between 5-10ppm nitrate, but now phosphates are being irregular and dropped to 0.02 from 0.07-0.09. I am not chasing a specific number, just want more consistency with my daily feedings to raise healthy fish and keep my corals happy as well. My target range is 5-10ppm nitrate and 0.04-.0.08 phos with some leeway upwards. I have neophos on hand as well in case it drops below that, as dinos seem to be a reoccurring issue in my system. Cyano is also having its way atm.

Since the tank is still new, 4 months, but everything was transferred from a 1.5year reef, I assume a lot of this is growing pains until it hits maturity.

Any insight is well appreciated. Thank you!

Do you use pre-portioned foods like frozen cubes? Yes, and I just break some off a frozen block

Are you taking nutritional analysis and converting the weight into PPM to calculate the exact amount added per feed? No, nerd! Tell us more. How do you account for metabolism of fish and coral etc.?

Or do you just eye-ball it and feed more when readings are low, feed more when readings are less? Who tests N and P more than once a month? People without kids, that's who.

2x a day can be 4x a day, feed more often is my take away. I have gotten phosphates up to .8-.9 with no real isues, and nitrates over 90 but don't do that. I like to keep phosphates around .3 and nitrates around 30. I have a post on my old 168 journal that goes into what I fed then. Keep asking more questions.
