While researching seaweed trace minerals on GulfCoast Ecosystems website, I found this reference to different products named Miracle Mud. While I have purchased more than one on the list, @PaulB had it right with MULM.

Suitable Substrates |
There are many suitable substrates for growing marine plants in the aquarium. The composition, depth and size of the substrate used is largely based on the individual species of macro algae or sea grass desired. Many commercial products are available to hobbyists for use with marine plants, but most are marketed for the refugium. Although macro algae does not derive any nutrients directly form the substrate, with the exception of sea grass, some type of substrate is usually needed for most species so that they can readily attach themselves. By far, the most popular substrate is the use of a fine grade aragonite sand at varying depths. Fine grade sand is readily colonized by most all Caulerpa species and is generally the easiest to maintain. There are also proven benefits to providing a deep sand bed to reduce nitrates and to culture marine fauna, but most macro algae species don't require any substrate at all. Sea grass, however, does require a deep sand bed as its root system can extend quite deep.
Careful attention should be taken to not introduce substrate to the aquarium that is too compacted, such as silica or quartz sand as this will most likely cause a dense anaerobic layer in the sand bed that can be toxic to tank inhabitants if disturbed. If a mixed macro algae and sea grass system is desired, it would need to devote some portion of the aquarium to a deep sand bed in order to successfully grow vascular plants. For the most part, a mixture of substrates will create an environment suitable for the addition of most any species desired.Most commonly available substrates are composed of variable amounts of aragonite and/or calcite. Aragonite is beneficial in its ability to properly buffer the aquarium water, helping to maintain both ph and alkalinity. Smaller grain sizes dissolve faster while coarse media such as crushed coral is much slower to break down requiring a higher ph to dissolve. Marine plants that do well in a fine to medium grade aragonite sand include most species of Caulerpa and calcified algae such as shaving brush & mermaids fan, as well as sea grass. Coarse media such as crushed coral, shell or live rock rubble can also be used to anchor marine plants and is a good choice if a deep sand bed is not needed, especially in the refugium. The only drawback to using coarse sand/rubble is that it tends to collect detritus and sediment, often becoming a nutrient trap over time. In marine plant dominated aquariums this can be an added benefit however, as high levels of nutrients are needed for long term success. Some invertebrates are better suited to this environment, such as amphipods, while other soft bodied invertebrates desire a less abrasive environment.
Most varieties of red and brown macro algae grow on rocks and hard bottom habitats in their natural environment, so a coarser substrate is more suited for anchoring. Marine macro algae such as Gracilaria, Botryolcadia, Sargassum and Halymenia can be glued or placed between rocks/rubble and will readily attach themselves. Most all macro algae are very adaptable, and will grow free floating or attach to most any surface, including substrate, live rock or even the sides or bottom of aquariums. Soon mud filters began to gain in popularity for use in the refugium. Several manufacturers began offering a product that would duplicate tropical coastal environments, such as lagoons and mangrove habitats. These products claim to provide a variety of trace elements including, calcium, iodine, strontium, iron, and free carbon. The idea behind using a nutrient rich substrate was to provide a replenishing source of nutrients by slowly releasing them into the aquarium water. Below is a brief summary detailing the most popular aquarium mud, its composition and qualities. Miracle Mud Manufactured by Ecosystems Aquarium Inc., this substrate is light tan in color with a wide range of grain sizes. The composition is very silty and must be topped with aragonite so as not to disturb the substrate. The manufacturer claims that this product contains over 68 naturally occuring elements. The replacement of approximately 50% of the substrate should be done every 12 months to maintain the slow release of nutrients. Mineral Mud Manufactured by CaribSea Inc., this substrate is a dark brown almost black mud which includes a mix of grain sizes including large chunks of sediment. This particular product is very silty and must be topped with aragonite or similar product to prevent it from clouding the aquarium water. The manufacturer claims that it contains simply "marine organics" created to mimic coastal marine environments. Fiji Mud Refugium Booster Manufactured by Walt Smith International Inc., this substrate is a wild collected organic mix harvested from Fiji. It is dark brown in composition and is designed to be topped with aragonite or similar product. No ingredients are listed except that it is deep water mud from Fiji. F.O.R.M Manufactured by Marc Weiss. F.O.R.M (funky old reef mud) is actually a additive that is added to the refugium to release needed nutrients. This particular product is a dark rich highly organic material derived from the ferment of seaweed. Marine Biosediment Manufactured by Kent Marine Inc., this substrate is a fine aragonite based sand containing calcium, magnesium, strontium, potassium, carbonate, sulfate and other trace elements. | |
