Been dosing phyto for a year
Tetraselmis phyto from Mercer, brewed using f/2 fertilizer also from Mercer.
The plan was to feed phyto so the little green phyto buggers would consume no3 and po4 and feed my corals (and pods)
In the past year, only 1/3rd of this statement has panned out for me
Dosing phyto is an excellent natural way to reduce no3 but does NOT effect po4 (based on my year long dosing and testing)
The f/2 fertilizer used to grow phyto has a boatload of po4 still in it when dosed.
My deep green brewed phyto reduces my no3 to 2ppm but raises my po4 to 2+ppm.
In my zoa tank I had to severely cut back on phyto bc my zoas weren't eating the phyto and stripping them of no3 nutrients
.... to the point where my zoa disc heads have been consistently shrinking to tiny lil heads
Found this disc shrinking NOT a "too much light" issue but due to lack of no3 nutrition.
I'm open to hearing discussions on other ppls experiences
