Iron and muds

[tinycrazycrawler]

I've read a lot about miracle mud, and from the analisis I've understood that is very enriched in Fe.
Maybe, all the muds success (Caribsea-miracle mud- seachem- Kent Marine) and the reason why they work well is the Fe binded to the substrate, so caulerpa can get it but the algae in the tank remain Fe- limited. Is this possibile?
What do you think about Miracle Mud and similar? Are they only a way to conduct a refugium or they are really a "miracle"?
Many thanks,
Marco

I never used miracle mud myself, and frankly I don't believe in miracles -- improvements yes, miracles, no.
