Co2 System

If you have a fish tank, it is, a good idea to have aquatic plants and reefs in it to serve as hiding places for aquatic animals, or to just have variety in the tank. To promote robust growth of these plants, a system providing a healthy dose of CO2 is required.

Durable, long-lasting and convenient, these CO2 systems are fish tank accessories that boast CO2 levels in the water to keep your plants happy, but not to the level where your aquatic animal pets complain.
