How much nitrates can corals tolerate? Varies by species? Is there a generally accepted threshold?

It really really depends. They are like fish. Some are extremely hardy some are not. Some corals don't do well in low-nutrient systems.

The general rule of thumb is keep nitrates below 20. But SPS usually won't tolerate nitrate at even these levels; they need nitrates as close to 0 as possible.
