Adding nitrate alone can be dangerous in this situation – for your corals at least.  It's somewhat likely that you should have added Phosphates first, or maybe even instead of Nitrates. 

 

I have quite a few articles on my blog that talk about nutrients and corals....but this one is probably the best single article to check out as it comes with the best visuals.  Notice the differences between corals in high vs low N and/or P environments, and which ones are obviously more healthy.  This mostly speaks to the importance of phosphate, but implies also what I was mentioning about Nitrates:

• Phosphate deficiency promotes coral bleaching and is reflected by the ultrastructure of symbiotic dinoflagellates

This great picture from that article might tell as much of the story as you need:

(Legend:  N=Nitrate P=Phosphate H=High L=Low)

 

These next articles are all reading/no pics, but they talk more about the nitrogen/nitrate aspect of the equation:

• Nitrogen cycling in corals: the key to understanding holobiont functioning?
• Impacts of nutrient enrichment on coral reefs: new perspectives and implications for coastal management and reef survival

 

There are probably a few more articles that address the nitrogen aspect of coral nutrition if you dig through the Coral or Nutrients sections.  The headlines aren't always the most suggestive though.....fair warning.  🙂 

 

(I'm not 100% sure what you mean by "crash" so perhaps you mean something besides coral problems.  Definitely sorry it happened – looks like you had some pretty nice growth!!)
