Will dosing bacteria to established tank outcompete older strains?

Tank looks great, your doin a fine job, exactly what is the problem?

For some reason I think bacteria is out competing the corals for nutrients. Corals aren't thriving. They're growing.. to a degree..have had success with euphyllia in previous tanks but they dont fully expand here. Sps not thriving or coloring up. Nutrients undetectable in the morning although feeding and dosing no3 po4 during photoperiod.. I'm just used to nutrients steadily climbing in my old tanks.
This tank is surviving.

Perhaps your corals love your system so much, they are consuming the nutrients, in which case you should add more. I’ve always been a glass half full sort of guy..

I wish. Adding more browns them out. It happens everytime. Alreading browned out monti cap becomes even darker..polyps retract, beautiful orange polyps though. Some acro skin will look like i rubbed them with my finger, like the texture changes.
Maybe I need to be more precise when increasing..or revise the n to p ratio..again..
