Miracle Mud - Any practical experience?

[Pescador]

I've been running mud in my refugium for at least 5 years, I don't have it set up exactly like the Miracle system and I do use skimmers. (2 in fact)
I don't dose trace elements, I figure my water changes cover it.
I grow mangroves and they really like it, cheato grows like crazy and there are tons of bugs and worms.
I don't believe that it is the magic solution with no skimming or supplements.
When I started in this hobby I found there wasn't one cut and dried method to reefkeeping and I tried to combine parts I liked from different methods.
I have no idea if it is any better than any other mud, I really doubt there is a magic ingredient that justifies the price but it seems to works for me so I stuck with it.
Just my 2 cents
