BTW reef, not having a go at you, just trying to get info on what this mud is, and why it's a miracle.

Its a product name. gets your attention. seems to work well.

After all, you have given zeovit heaps over the years for exactly the same thing - not telling people whats in the formulas and evidence that it works.

the last time i read the packet it says what is in it. unlike some product who say nothing.

Once again all systems we use are a tool so you have to work out what you want to achieve and what time you want to spend doing it.

Is like a tennis player, they dont use all the same tennis rackets so they get one that suit there needs.

Unless your are Roger Federer who could be using a tooth pick and still beat us all.

Conclusions

The analysis indicates that Miracle Mud is 30% silicon. This mostly likely exists in Miracle Mud as silicon dioxide, which is most commonly found in nature as quartz. As pointed out by chemist Randy Holmes-Farley, the molecular weight of silicon makes up less than half the molecular weight of silicon dioxide. So if the silicon present is all in the form of silicon dioxide, then Miracle Mud is more than 63% quartz sand. This seems to be confirmed by the photos.

The high levels of metals (especially Aluminum, Iron and Titanium) are also a point of concern.

In addition, no traces of any marine sediment were found in any microscopic examination - no oolitic sand grains, no shell fragments, no diatoms or any other remnants of marine life. An acid test conducted by Shane Graber indicates that no carbonates are present in Miracle Mud. It is difficult to reconcile these facts with the manufacturer's claim that "Miracle Mud is 80% oceanic mud."

Obviously the miracle mud is suppling nutrients to the macro algae?

Sure it must be and suppling slow release iron, minerals etc.

I wonder how close miracle mud to mangrove mud in nutrition value

Not the same,

MM has slow release vitimins /minerals added, so that is why you have to change 1/2 every two years.

The thing is Drifty, how would your colour and growth be without it??

Better, the same?? I guess thats the problem in this hobby, you don't really know how these product (most of them, not just MM) affect your tank simply because we are not running an identical tank alongside to act as a test.

Your right, each to there own, not meaning to offend.

Yeah I think your correct puttputt, I am not sure how my tank would look without it. I am happy with it though.

Update photos of the caulerpa growth.

Pretty outstanding.

Please pm if you want some as i am ready to trim and throw it out.
