The Exo Terra Moss Ball helps provide crystal clear water and reduce odors. Designed to resemble its natural counterpart, the Exo Terra Moss Ball contains a special absorption resin that helps reduce many of the compounds that encourage unsightly algae. By absorbing and trapping phosphate, nitrite and nitrate within its core, the Exo Terra Moss Ball helps to create ideal conditions for animals and plants and makes aqua-terrarium maintenance easy.

Features:

• Traps phosphate, nitrite and nitrate
• Easy and effective deodorizer
• Reduces algae
• Effective for up to 2 months
• Treats 30-60 liter (10-20 gal) terrariums

Directions: Place Exo Terra Moss Ball into the water part of the terrarium/aqua-terrarium. Depending on the water volume, replace with new Exo Terra Moss Ball every two months for maximum effectiveness.
