The SodaStream Terra is a convenient and eco-friendly way to enjoy sparkling water at home. But if you’re tired of frequent CO2 refills or looking to save money, there’s an easy way to upgrade your setup. In this guide, I’ll show you how to replace your SodaStream CO2 bottle like normal and, for those who want a more cost-effective option, how to connect a larger CO2 tank using a conversion kit.

Step 1: Replacing Your SodaStream CO2 Bottle

Replacing the CO2 bottle in your SodaStream Terra is simple and takes just a few steps:
1. Unplug the SodaStream: Safety first—disconnect the machine from any power source before starting.
2. Remove the Empty CO2 Bottle: Lift the handle at the back of the machine to release the old bottle. Slide it out gently.
3. Prepare the New Bottle: Remove the wrapper and cap from your new CO2 bottle.
4. Install the New Bottle: Insert the base of the bottle first, then slide the top into place. Press the handle down to lock it securely.
5. Plug It Back In: Once the bottle is in place, reconnect your SodaStream and you’re ready to carbonate.
It’s a straightforward process, and you’ll be back to enjoying fresh sparkling water in no time.
Step 2: Converting to a Larger CO2 Tank for Big Savings
If you go through a lot of CO2, upgrading to a larger tank can save you significant money over time. A conversion kit allows you to connect your SodaStream Terra to an external CO2 tank, giving you more carbonation for less cost.
How the Conversion Works:

• What You’ll Need: The CO2 adapter kit connects your SodaStream Terra to large CO2 tanks, such as 5lb, 20lb, or even 50lb commercial tanks. Make sure your tank has a CGA-320 outlet, as the kit is designed for compatibility with this standard.
• Easy Installation: The adapter hose attaches securely to your SodaStream Terra and the external tank. The 60-inch hose provides flexibility, and the lightweight design makes setup easy.

• Food-Grade Materials: Both the hose and o-rings are made of food-grade materials, ensuring your sparkling water retains its taste and quality.
Cost Savings:
Switching to a larger CO2 tank can save you up to 70% compared to regular SodaStream refills. With a 20lb tank, you can carbonate thousands of liters of water before needing a refill, making it a great option for families or frequent users.
Safety Tips for Replacing and Converting CO2 Tanks
• Release Pressure: Before removing any CO2 bottle, ensure there’s no pressure left in the tank by pressing the release valve.
• Secure Connections: When installing the adapter kit, double-check all connections to ensure they’re tight and free of leaks.
• Store Tanks Safely: Keep large CO2 tanks in an upright position in a cool, dry place away from direct sunlight or heat sources.

The SodaStream Terra is not only easy to use but also eco-friendly. It eliminates the need for single-use bottles and offers customizable carbonation at the push of a button. Paired with a larger CO2 tank, it becomes a powerful and cost-effective tool for anyone who loves sparkling water.
