According to the release page for the new update that included the Moon Pool, its location is the Grand Reef. I think I may have found this place once - look out for floating underwater islands, then dive down to 250 - 400 metres. I cannot confirm this is where you'll find the fragments as I am still looking myself, but I strongly suspect it is the right place to look. Take a cyclops or seamoth and a rebreather along or you'll have trouble with oxygen.

If I find the exact location I will let you know. For now all I remember is that I passed from an area carpeted with red seaweed through a large forest of creeper in order to reach it.
