what is algae control philosophy, with empirical support?
They used to say that limiting one nutrient, like phosphate, could keep algae in check vs plants. Now the norm seems to be EI, providing all nutrients plants need without limits. Is the philosophy then that, when plants have everything they need, they successfully out-compete algae? In other words, what keeps algae (but not plants) in check in a healthy planted tank? And do we have experimental evidence to support our answers?
thanks for enlightening me!
