Sadly there’s no one in my area that reefs , stores are scarce , I just can’t believe they really are that high and the corals are doing amazing I don’t know what to say to be honest and part of me wonders if I start Gfo or this bacteria product I’ll regret it but I know .30 po4 is not okay what about gfo in a bag ? Not a reactor ?
My tank is running .2-.3 P04 and grows acros just fine.
Every time I've ever tried GFO, my acros hated it. Had much better success with LaCl.
If things are growing as good as you say, I'd just leave it be. If your tank wants to run at .3, then, it wants to run at .3. As long as it's stable and not rising, I wouldn't mess with it.
