I usually soak in RODI for 3-4 weeks, stir it when I remember and change the water every week. This is my first time using the Korallin media and the pieces are a little smaller and appear more dense. I also noticed more pieces of shells versus the ARM media. (Don't know if that matters or not.)
I soak my calcium reactor media also, it really helps remove all the po4 from the media. Not sure if the shells contain phosphates, but I know ARM claims their product contains very little shells.
Hope your tank is doing better!
