on a true reef, algae would easily grow, but a abundance of grazers keeps it in check, many of the reefs in poor health are that way because of removal of the grazers
Definitely this. We see the effect of nutrient runoff entering seas and causing algal blooms. Overfishing has also been shown to effect reef health.
Nature is a balancing act and man interfering causes problems. We see algae taking over when we strip parrotfish from the reefs and we see kelp destroyed by urchins when their population blooms because their predators were taken.
With us keeping such a high fish population in a tank we are effectively dosing n and p, which is the biggest reason we need such a robust nutrient export system.
