David,
I know it seemed a little harsh, but Rich is just trying to help. I too have gotten a little out of line (sometimes a lot) because we do get pissed off with nonsense products. We get even more pissed off when someone posts a link which is nothing more than an advertisement by the company selling the product.
Now, if this helps, I've used Miracle Mud in the past. I have nothing good to say about it. I don't feel it did a thing for my system besides yellow my water. I did some research and found that Miracle Mud is made up of about 70% quartz which doesn't benefit our tanks in any way. I had better results when I removed the mud.
As we should all know by now, products advertised as "Miracle", "Amazing Reef Vitalizer" and such are always flops. This sums up Miracle Mud and Marc Weiss products nicely. Snake oil. False claims in a hobby that has no regulations in advertising.
Now to answer the question, if it were my tank, I'd go with very large remote DSB with high flow that can be pulled off line and changed every 5 to 6 years. But at the same time, providing more info would help. Is there sand in the main display? Do you need a refugium (I feel most claims regarding refugiums is false)? What are you keeping?
