This single magnetic frag rock provides a natural-looking mounting surface for coral frags while allowing placement on aquarium glass. Its compact size makes it easy to position frags exactly where needed without disrupting the overall aquascape.

Embedded fully sealed neodymium magnets allow the frag rock to be securely held in place on aquarium walls and can be completely submerged. The magnet strength is fixed and cannot be adjusted.

The textured rock surface supports coral attachment and encourages natural encrusting over time, helping frags blend naturally into the surrounding reef structure.

Founded in 2001, our brand is dedicated to creating durable, reef-safe aquarium decor designed for long-term use.

Safety Notice:
Not intended for children 14 years and under due to small magnets.

Care Instructions:
Rinse with fresh water before use. Do not use bleach or harsh chemicals.

Distribution: Macrocystis pyrifera is common along the coast of the eastern Pacific Ocean, from Baja California north to southeast Alaska, and is also found in the southern oceans near South America, South Africa, Australia, and New Zealand.

Description: Macrocystis pyrifera, commonly known as giant kelp or giant bladder kelp is the largest of all algae. The stage of the life cycle that is usually seen is the sporophyte, which is perennial and individuals persist for many years. Individuals may grow in excess of 50m (160ft) long. The kelp often grows even longer than the distance from the bottom to the surface as it will grow in a diagonal direction due to the ocean current pushing against the kelp. The stalks arise from a holdfast and branch three or four times from near the base. Blades develop at irregular intervals along the stipe, with a single pneumatocyst (gas bladder) at the base of each blade.

*Price includes terminal blade and rock anchor.

These floating habitats play a vital role in marine ecosystems by providing food, shelter, and breeding grounds for a wide variety of sea life, including fish, sea turtles, crabs, shrimp, and seabirds.

Our artificial Sargassum is carefully designed to replicate the natural look and function of real brown algae, making it perfect for use in aquariums, exhibitions, or creative underwater installations, whether for aesthetic or practical purposes.

Please note: The numbers shown under “Size” (8, 12, 16, or 24) refer to the total number of individual fronds combined to create one complete piece of artificial Sargassum.

This is not the quantity of separate units you will receive, but the amount of fronds used to build the overall size and fullness of one Sargassum piece.

The higher the number, the larger and denser the final product will be.

Leaf Count: Typically 10 blades per unit
Leaf Width: Approximately 10 mm

Distribution:
The genus Zostera exhibits a broad distribution, occurring along coastal regions of the Northern Hemisphere, as well as parts of the Southern Hemisphere including Australia, New Zealand, Southeast Asia, and Southern Africa. The discovery of Zostera chilensis in 2005 extended the genus’s known range to the Pacific coast of South America. Additionally, Zostera noltii has been recorded along the inland shores of the Caspian Sea, representing an atypical, land-locked occurrence for the genus.
