Spawning Sea Urchin

My Sea urchin spawned just spawned today for about half an hour (it's a male). I think it spawned because I couldn't find any water to replace the water that evaporated which caused the salinity to go up and then I got some water about a day later and I put some in which would have caused the salinity to go back to normal which I believe caused the urchin to reproduce. It was really interesting to watch.
 
FWIW my trochus snails spawned that day as well...

check the moon calendar ;) It was a full moon on the July 15th IIRC.
