It's a novel idea, as Brian mentioned I too am not here to discourage. These are just things we need to look at when we attempt our little "projects".

I completely agree, I think there is a huge responsibility that rests on anyone's shoulders if they thought they were doing a certain area of a
reef a favor by introducing a new species to that area. We think we know so much, and yet we really know so little about the 'whole picture', when it comes to a complete
ecosystem and how every little creature functions so beautifully together.
It's hard to imagine that introducing something so tiny as a
copepod or daphnia to a new environment could make a huge impact, but it definitely could, and I certainly wouldn't want to be the one that caused that. Luckily, that's not the intent of my project. The reason I'm converting the daphnia is because I'm looking for a good food source for larvae, something easy to grow, has a high nutritional value, is pelagic and has an extremely small larval size. If I was doing this just to see if I could do it, well,....I've got better things to do. ;-)
I don't think you could convert just anything. I had actually heard from a friend of mine in Germany that daphnia are tolerant to brackish if you adjust them slowly. I'm just trying to push that limit.
