Wanted to throw this question up in the forums as I caught myself researching but didnt really find an answer.
Point 1. So we use GFO (ferric/iron oxide) to remove PO4 from water, and the only prophylactic prior to its use is a good rinse to get rid of dust.
Point 2. I see a number of posts on the forum everytime corals retract, fish act weird, etc, etc, people always say to check your equipment for rust which is also an iron oxide.
I was hoping someone with a chemistry background could provide insight as to why GFO is generally recommended for use, but rust can be "problematic" in a tank.
Thanks,
Nature.
