I'm using melted bagged ice as my water source do i still need calmag???
You say you are using distilled water, that means it has no nutrients, and the ph is "neutral" which is a PH of 7. That ph needs to be give or take in the region of 5.5
I have never heard of anyone using packing peanuts as a medium, so I can't really comment on that... but I would use a proven method instead of experimenting with something like that.
