XXL Marimo Moss Balls 7-10 cm

Marimo Moss Balls XXL 7–10 cm from Ekomoss

We present a true natural wonder for your aquarium — the majestic Marimo moss ball from Ekomoss in an extra‑large 7–10 cm size. This giant moss ball is the ideal decorative element for experienced aquarists and is guaranteed to become the central eye‑catcher. Scientifically known as Aegagropila linnaei, it is not an ordinary plant, but a colony of the fascinating green alga Cladophora that has grown over decades. Its perfect spherical shape and velvety green texture make it a living work of natural art.

Advantages and special features

• Living biofilter: The huge surface area of this 7–10 cm ball acts as a powerful biofilter. It provides an ideal habitat for beneficial bacteria that form a dense biofilm. These tiny helpers tirelessly purify aquarium water by breaking down organic waste, detritus, and pollutants. As a result, water quality improves noticeably and water parameters remain stable.
• Paradise for shrimp: This large Marimo ball is especially valuable in invertebrate aquariums. For dwarf shrimp, it offers a vast grazing area whose biofilm provides a constant, nutritious food source. It is fascinating to watch the shrimp graze on the ball. In addition, the dense structure offers countless hiding places and crevices where especially juvenile shrimp can safely retreat from predators.

Creative use and care

The Marimo moss balls from Ekomoss are extremely versatile. While the beauty of this XXL ball is best showcased when it rests whole on the substrate, there are also creative alternatives. It can be carefully divided into smaller pieces to create unique elements for aquascaping or attached to rocks and driftwood to imitate a dense, moss‑like carpet.

Care is very simple. To maintain the perfect round shape and avoid unsightly brown spots, the ball should be turned regularly so that all sides receive equal light for photosynthesis. For cleaning, it can be removed from the tank during a water change and gently rinsed under running water to remove accumulated debris.
