Rinsing food and Refreezing

[ScubaSteve]

Yeah, I've always wondered the same thing. I avoid the brine shrimp partly because of this (and because they're low in nutritional value) but I will feed mysid shrimp. I'll let my mysid soak in RO/DI for a bit to thaw and try to draw some of the N/P out, rinse, then feed.

I don't think the mysid, for example, have high N/P in their bodies as they are farmed from a lake up North and are flashed frozen rather than processed in the way a prawn would be. I laways rinse them to remove the liquid they were frozen with.

It'd be great if a manufacturer could give some details on things like N/P.
