Frequently Asked Questions regarding Fiji Mud
Q) Why is mud so important to my refugium set up?
A) Mud harvested from the ocean in clear water patches will contain all of the essential minerals and trace elements that are found in the sea in their natural state and composition. When your water passes over this concentration of minerals and elements in your refugium, it carries with it some of the most important nutrients that you can furnish your system in its natural state.
Q) How long will Fiji Mud last in the package on my retailer's shelf?
A) As long as the product remains moist you can be sure that it will still have the active ingredients and minerals required to maintain the integrity of this product. Since this is the only product that is actually harvested on the reef in the South Pacific, it is truly unique in its composition and ability to benefit your captive reef system.
Q) How often will I need to add more mud to my refugium?
A) Some of the mud will naturally dissipate into the water column as the water flows over it. The change will be gradual and every tank or refugium will be different depending on flow. In general, it is a good idea to watch the level of mud and when you see it start to go down just add a little more. The standard height of mud in your refugium should be about 1-1/2 to 3 inches depending on the algae and plants you are also trying to grow in the refugium.
Q) Do I need to replace any of the mud because the nutrients are used up?
A) The mud will naturally replace some of its own nutrients in the normal cycling and growth of the algae. However, it is recommended that every 4 to 6 months you do replace about 20%-30% of the mud for a more vibrant and robust bed of fresh minerals and trace elements.
Q) If I do not have a refugium can the mud still benefit me?
A) If no refugium is currently being used in your system then the mud can still be used to benefit your reef with the essential (and all natural) minerals. This can be accomplished by simply adding some of the mud into your substrate on a regular basis.
Q) I already have live sand in my refugium, can the mud still be added or do I need to discard the sand?
A) There is no need to discard the sand and it is not recommended to do so. The mud can be easily added to the sand by either putting a layer of about 1-1/2 inches on top of the sand or by mixing the sand and mud together. This will greatly benefit all of the advantages that your refugium is designed to provide.
Q) When I place the mud in my refugium should I expect the water to become cloudy and (if so) will this harm my tank?
A) Whenever you place mud in your tank, you should expect the water to cloud up for a short period. If some of the mud settles on your corals do not worry, this happens in the ocean all the time and all you have to do is create some wave action in front of your corals to blow it off. However, the best way to add the mud is to turn your refugium off when mixing the mud in and let it stand until the mud settles in the refugium (usually 30 minutes to one hour) then restart your refugium for best results.
