New Fluval Moss Balls from Hagen Absorb Harmful Substances and Clean the Water in Aquariums

MANSFIELD, Mass. The Rolf C. Hagen (USA) Corp. has tapped into the surging popularity of Marimo balls – clusters of live filamentous green algae that actually control algae in aquariums – by developing its own Fluval Moss Balls, an attractive way for aquarium enthusiasts to reap the benefits of the trendy Marimo balls in an easy-to-maintain way that preserves the look of their biological equivalents.

While Fluval’s Moss Balls won’t battle with other algae for nutrients as live Marimo balls do, they are designed to keep the water clean, and they do this by functioning in much the same way as their natural counterparts by absorbing and helping to reduce many aquarium compounds that encourage odors and unsightly matter accumulation, with the added bonus of being easier to care for.  The realistic “moss” covering of Fluval’s Moss Balls gathers molecules in the water that produce harmful substances and the internal core, which is made of a special resin, absorbs and traps phosphate, nitrate and nitrite, reducing accumulation of organic matter and preventing algae buildup to help create clean, crystal-clear, odor-free water and ideal conditions for fish, shrimp and plants.  Additionally, unlike real Marimo balls, there is no concern over Fluval’s Moss Balls growing too large for the aquarium space, since they are not living things.  The Moss Balls are about the size of a medium Marimo ball, dimensions that can be accommodated by most tanks.   

Fluval’s Moss Balls can be placed in an aquarium or the water part of a terrarium.  One Moss Ball is sufficient to clean the water of a 30-60 liter (10-20 gallon) aquarium; for larger set-ups, multiple Moss Balls may be used.  There really is no maintenance involved with Moss Balls – simply change the Moss Ball every two months for maximum effectiveness.

Fluval’s Moss Balls measure 2” in diameter and have an MSRP of $5.49.  They are available online and at pet retailers nationwide.  For more information visit, or contact the Rolf C. Hagen (USA) Corp. at 1-800-225-2700.
