The bio pellets consumes PO4 and NO3 in the ratio that is needed by the bacterias so it will reduce both PO4 and NO3 at the same time and because of that one will not become depleted before the other unless specific removers such as GFO or nitrate removers are used. plus anytime you feed the fish you are adding PO4 and NO3 into the system which in turn feeds the bacterias. 
But in the case that one nutrient gets limited, you will observed either PO4 or NO3 hovering at a range and not changing but that is purely hypothetical and does not happen in real life. |
OK, thanks for the clarification!
