GLA Black CO2-Resistant Tubing (10 Feet)
The GLA Black CO2-Resistant Tubing is designed specifically for pressurized planted aquarium CO2 systems.
Unlike standard silicone airline tubing, which allows CO2 gas to slowly escape through the tubing walls, this tubing is engineered to reduce CO2 loss and maintain efficient, stable CO2 delivery.
The tubing remains flexible enough for clean routing and installation while providing the pressure resistance required for reliable planted aquarium CO2 systems.
The black finish provides a clean, discreet appearance that blends easily into aquarium cabinets, backgrounds, and equipment layouts while maintaining long-term durability and pressure resistance.
- High-pressure rated for aquarium CO2 systems
- Designed to minimize CO2 gas loss
- Black finish for clean, discreet aquarium installations
- Compatible with standard aquarium CO2 equipment
- 10 foot length
Sold in 10 foot sections. Multiple quantities will typically ship as one continuous uncut length whenever possible (example: qty 3 = 30 feet).
Compatible with GLA and Atomic aquarium CO2 equipment including regulators, diffusers, reactors, check valves, and bubble counters.
Note: This is CO2-resistant tubing and is not standard silicone airline tubing.

Co2 tube
Great tube. Good quality.

Strong Sturdy Line
I just got everything hooked up yesterday. You can tell this line is quality when you go to cut it with scissors. You have to apply a good bit of pressure compared to standard air line.

Thick and sturdy
This tubing is much thicker than the CO2 tubing that came with my Fluval kit. I'm sure it will hold up for years. It's a little tricky to work over the hose barbs but once it's in place it's fine. The black blends nicely into the aquarium decor but I did realize I can't see whether my check valve is working unless water backs all the way up to the bubble counter. Just something to keep in mind. I'm probably going to buy some clear tubing for the run between the check valve and regulator.

High Quality
Well made tubing, although a touch hard to connect to my in-tank diffuser as it’s very rigid. Heating it in warm water didn’t soften it too much. I expect it to hold for many years, and would purchase again.

High quality
Very high quality tubing. It is a major improvement over regular airline tubing.
