Nutrients to ALK Ratio?

[Bear22]

Guys,

My alkalinity seems to be on autopilot at around 9.5dKH with pH usually between 8.2 to 8.4. I'm already using a "low" alkalinity salt mix with TM Pro. I do a weekly water change.

At these levels what NO3 level might be a good target to shoot for? Does PO4 need to be tweaked as well?

TIA

Following. I didn't think there was a real relationship between these.

Just keep both in a reasonable range.

The only thing I've heard can be bad is low nutrients with high alk. Have no idea of ratios. I've never thought of trying to keep N and P at a certain level related to alk.

I've always had more success by focusing more on stability in the right range rather than a ratio. Nitrate 10-20ppm phosphate .08-.12. If the test is outside this range, I'll try to slowly correct over the next month.
