A unique blend of sediments that duplicate tropical fringing coastal mangrove environments.

Mineral Mud™ particles are in a size range compatible with soft, burrowing infaunal, macro animal assemblages. Ideal for mud refugiums, seagrasses, macro-algaes, and mangroves, Mineral Mud™ provides a variety of trace elements plus calcium, strontium, iron, sulfur and free carbon. In addition, Mineral Mud™ contains live marine bacteria to complete the tropical ecosystem.

Frequently Asked Questions

In what type of reactor would I use Mineral Mud™?

Mineral Mud™ is actually a refugium media that is meant to be used in a refugium type aquarium with lighting and with plants and algae growing in it. Mineral Mud™ quickly establishes an anaerobic denitrifying bed and acts as a wonderful media for growing most types of marine aquatic plants and algae. This creates an ideal environment for nutrient export, (through algae and plants), and micro faunal growth. It can be used alone or with a ½ to 1” cap of live or dry aragonite


For mud filters, empty jar into filter, then mix slightly, and add water (a “cap” of approximately 1/2 to 1 inch of live or dry aragonite sand is suggested). Wait 2-3 days, then begin pumps, and allow system to clear water (may take 1-2 days). Then add macro-algae, seagrasses, or mangroves. Allow tank to cycle, then add fish and corals into main tank. If using Mineral Mud™ in main tank, mix into a small area where you intend to plant your macro-algaes, seagrasses, or mangroves. Do not cover the entire tank bottom.

Run pumps for a day or two until water clears, then add plants.

NOTE: This substrate contains marine organics, and was created to mimic coastal marine mangrove environments. It is designed to reach anaerobic conditions within an inch of the sub-strate/water interface. Once established, avoid disturbing the bed.

Orders over £30 are Delivered FREE!

Providing none of the items in your order require pallet delivery or are excluded from delivery promotions, we will give you free standard delivery. You can still upgrade this service if you wish, and will only pay the difference.


Pallet Deliveries are different.

For items that have to be sent by insured pallet or other special delivery, these are excluded from the standard delivery offer and instead follow a different system. Pallet deliveries are split into 2 tiers: tier 1 and tier 2. Pallet deliveries take 2-4 working days and cannot be tracked.


For pallet deliveries we will contact you to confirm the delivery address and delivery day before releasing the order.


Please note that the pallet delivery service is a drop at kerb only service, the drivers are not insured to handle goods into homes and you are required to dispose of the pallet.


Pallet Tier 1

This tier is for solo tanks and cabinets, or other solo high weight products that we can't send by a normal courier. We subsidies the majority of the true delivery cost for these items to offer the best value we can. The shipping cost for these is calculated at checkout.


Pallet Tier 2

New for 2020! We are proud to announce we now offer FREE mainland UK pallet deliveries for Pallet Tier 2. Pallet Tier 2 is for the larger full tank and cabinet sets, such as the beautiful Juwel Rio, Lido, Trigon and Vision ranges.
