I realize that undetectable is not absolute zero, but if a coral is nutrient limited it can absolutely slow growthYou can have photosynthesis taking place and still have undetectable nitrates and phosphates. Think for a minute and you’ll see why.

+1, this was going to be my response, we have closed systemscorals have multiple other food sources we can't replicate in our tanks.
On the reef, there really aren’t so many food sources. In fact, I think you can lump them into two groups. Sunlight and fauna. And both can be replicated, to some extent, in our aquariums.+1, this was going to be my response, we have closed systems
they eat more bacteria and organic material then zooplankton and lightOn the reef, there really aren’t so many food sources. In fact, I think you can lump them into two groups. Sunlight and fauna. And both can be replicated, to some extent, in our aquariums.
Both those torch corals, the gold and the green fade started out as 2 inch frags. About the size of the one in the middle.I think if yr corals are over 2 years old they could be a heck of a lot bigger provided more nutrients
I don’t think pristine water, such as the water in a tropical reef, would hold large quantities of bacteria. The bacteria have to eat too, don’t they?they eat more bacteria and organic material then zooplankton and light
most probably have plenty organics... perhaps carbon dose for bacteria

That’s the variable that I think causes a lot of tanks to crash. Trying to meet the needs of so many diverse animals. SPS taken off the reef are going to have different needs than a coral taken out of turbid water. JMHO.I think we need to keep in mind many keep mixed tanks with different types of corals from different parts of the world. Some having very different light or flow or nutrient ideal conditions from the next coral.
