Yes, this is confusing. Some research been done with N:P and some with NO3:PO4.
N:P of 10:1 = NO3:PO4 of 10:0.69
Usually, in this hobby, we use NO3:PO4 because our test kits measure NO3 and PO4. In practice, ratio NO3:PO4 of 10:0.69 works great for plants. Keeping it that way is another matter. To maintain this ratio in the water column, dosing NO3:PO4 of 10:1 to 10:3 is needed.
