I've used MM. I removed it about 9 months ago and guess what...
Nothing happened, because I had enough redundant filtration on my tank that it didn't matter. The mud really didn't do much for me other than leach iron into the water (it seems to be very good at that, the lab analysis shows it is high in Fe).
That being said, it can work just as a deep sandbed would. It is a nutrient sink. The problem is, nutrients will eventually build up in the mudbed, and it will start to leach those undesirables back into the water once it hits the saturation point.
What billsreef said is spot on. It will work as a great nutrient sink for a while, but will eventually become saturated. I know Leng Sy even recommends replacing the mud after 6 months to 1 year for this reason.
Chingchai uses it in his beautiful aquarium, but he has a lot of other filtration methods as well.
