Compatible with the Fluval Mini Pressurized CO2 Kit and other planted tanks, these cartridges deliver precise CO2 dosing to support vibrant, lush aquatic plants and balanced fish habitats. ## Description Since all planted aquariums lack CO2, it is extremely important that they are supplemented with it. In fact, 40 to 50% of a plant's dry weight is composed of carbon. For optimal condition of aquarium plants, some CO2 supplementation is necessary. The Fluval Mini Pressurized CO2 Cartridges are a pack of three cartridges that are replacement parts for the Fluval Mini Pressurized CO2 Kit. Proper amounts of CO2 are important to ensure that the most vital nutrients are available to live plants to maintain vigorous, lush and vibrant growth and condition.Fluval first broke onto the aquatic scene in 1975 by introducing the world’s first 3-stage filter with synchronous motor technology – a landmark breakthrough that is still applied in the industry today. Since then, Fluval has built a legacy around this pioneering spirit, relentlessly adapting in a changing world to launch innovative aquarium products that remain at the forefront of technology, and which set the bar in quality, style and functionality. Above and beyond its manufacturing role, Fluval prides itself on its charitable and educational efforts that give back to the fishkeeping community, whether it means helping to fund the protection of wild coral reefs or jumping on a plane to document endangered fish species halfway around the world. Fluval’s mission is not just about building products that mimic the natural world, but inspiring aquarists of all skill levels to enjoy and respect the hobby for generations to come.
