Is it really gone or is it that the lack of whites make us not see it?work threads are different. when you have 20 GHA tanks given to you in one place to work, methods that reduce growback are quickly found.
I can cause gha in otherwise controlled tanks if I just twist the kessil dial the opposite way.
I can grow algae in any reef tank in the world by shining a 6K HPS light meant for growing vegetation on it.
much like how old vho bulbs tended to cause cyano, and abate when updated.
that doesnt mean many home tanks arent tuned to run just fine on 10K, yours is agreed.
blue balance is a core aspect of work thread management and getting compliance in a high degree of worked systems but only in algae challenge or cyano threads, for a normal tank if its not expressing those invaders/white is np
we specifically start all dry start reefs with heavy blues, whites will just fill it all up with GHA totally, each surface reflecting all directions/growth potency
I write this because blues hide my algae.
@brandon429 i totally respect your work so please don’t take this as argumentative. It’s a real question.
