CO2 System Regulators and Accessories for Aquariums

Enhance plant growth in your aquarium with carbon dioxide (CO2) tank regulators and accessories from AFA.

About CO2 Systems for Aquariums

You need a CO2 system for your aquarium to ensure precise CO2 dosing for optimal plant growth. Without enough carbon dioxide, the plants in your aquarium cannot complete photosynthesis. Too much CO2 could suffocate fish and shrimp.

AFA carries the parts and accessories you need for your CO2 system setup, including:

• CO2 cylinders: Shipped empty, our durable aluminum cylinders come in different sizes — have them filled at a local gas supply or welding shop to provide your tank with the air it needs.
• CO2 regulators: CO2 tank regulators allow you to use the air in the cylinder safely, bringing it to the appropriate bubble rate for your tank. Some models include adapters for connection to a paintball cylinder.
• Pollen glass: Available in various sizes, pollen glass diffusers create fine bubbles so CO2 can more evenly and effectively dissolve in water.
• Glass counters: A bubble counter measures the CO2 supply so you can make small adjustments as needed.
• Solenoids: Control the flow of CO2 electronically with a solenoid. Connect it to an electronic timer to release CO2 as needed, like turning CO2 on and off in sync with aquarium light.
• Drop checkers: Use a drop checker in your CO2 system to easily monitor for the proper dosage. A pH reagent inside changes color based on the amount of carbon dioxide in the water.

With these items and other accessories, you can improve CO2 distribution in your system and make it easier to get the healthy aquascape you're after.
