I just use a DSB in my fuge. It has some rock rubble on one side of it for pods to grow and the rest is for macros! Also many worms, etc thrive in the DSB. So no mineral mud for me, but thats just me!

I used the miracle mud in my fuge when I first set it up. Never noticed any change in the tank or health of the corals or fish. Not trying to bash the product but won't use it again. Seems like it's claim to fame is that it helps replace trace elements in the water and seems to me I do that monthly with 20% water changes.
Works great for me. But it's not just the miracle mud...it's the calurpa you grow in it that you also benefit from. I would use it again in a heartbeat. I also have a DSB in my main tank.
