What's interesting in my tank is that the algae, including hair algae has completely disappeared with my bio pellets treatment. Yet my current N03 (20) and P04 (.30) is still much higher than others that do have hair algae. Rock that used to be covered in red and green carpet type algae (with trapped detritus) is now clean and shiny with just coralline growth. I think my regular MB7 dosing has had something to do with this, too, and created beneficial bacteria that out competed with the bacteria that might have been providing food to the algae or help it to consume the N03 and P04.
I'm not a chemist or biologist, so just my uneducated theory....
