How Long will the SodaStream Cylinder Last?

SodaStream Cylinder Usage Guide (Assumes High-Tech 30PPM setup. Lower-tech with less plants require less CO2.)
Aquarium Size	Recommended Dosage (Bubbles Per Second)	Estimated Run Time (Lifespan)
60L – 80L	1 to 1.5 bps	3.5 to 5.5 Months
100L – 130L	1.5 to 2 bps	2.5 to 3.5 Months
150L – 180L	2 to 2.5 bps	2 to 2.5 months
200L – 250L	2.5 to 3.5 bps	1.2 to 2 months

Why Inject CO2 Into Your Aquascape?

Carbon dioxide (CO2) is the primary building block for all aquatic plant life. While wild ecosystems enjoy an endless natural supply, home aquariums quickly deplete their available carbon. Supplementing your tank with a CO2 system unlocks:

Vibrant Coloration: Promotes deep reds and lush greens in demanding aquatic plants.
Thicker, Faster Growth: Accelerates carpet coverage and stem density.
Natural Algae Control: Robust, healthy plant growth is your single best natural defense against nuisance algae

Component Description:

SodaStream Adaptor: Converts standard NZ SodaStream threads to a standard NZ CO2 cylinder thread (W21.8). Features a built-in adjustment valve to safely control raw output from the cylinder.

Mini Dual-Gauge Regulator: Allows you to fine-tune and dial in your precise bubbles-per-second. The dual gauges display both input pressure (how much gas is left in your cylinder) and output pressure (the pressure actively being used).

Bubble Counter with Built-in Solenoid: Easily monitor your dosage by eye. The integrated 12V electronic solenoid lets you automate your CO2 schedule using a standard timer switch or an inline app controlled timer (sold separately).

High-Pressure Check Valve: A specialized inline non-return valve. It stops aquarium water from siphoning backward into your equipment when the gas turns off, protecting your solenoid and regulator from water damage.

SodaStream Base Options: It is critical to keep your SodaStream cylinder standing upright to prevent liquid CO2 from entering and damaging the regulator components. To solve this, we have designed two beautiful base options: a Simple Base and an Enclosed Base. Both are custom designed and made in-house using premium 3D printing technology by KiwiAqua Design Studio.

Quick Set Up & Operational Guide:

Set Up Guide:

Step 1: Prepare the Adaptor:

Ensure the adaptor dial is turned completely to the OFF position and verify the rubber sealing gasket is sitting inside. Screw the adaptor firmly onto your SodaStream cylinder.

Step 2: Attach the Regulator:

Thread the Mini Regulator onto the SodaStream adaptor. Tighten this hand-tight only—do NOT use tools or wrenches, as over-tightening can damage the seal.

Step 3: Prep & Mount the Bubble Counter:

Unscrew the top cap of the bubble counter and fill the clear chamber 2/3 full with water. Firmly push the bubble counter assembly directly into the regulator port. (Note: The connection is designed to feel slightly loose; this is normal).

Step 4: Run Your Lines:

Connect your CO2 tubing from the bubble counter to your check valve, and then to your diffuser. Crucial: Ensure the arrow printed on the check valve points toward the direction of the airflow (towards the aquarium).

Operational Guide:

Step 1: Double-check that both the adaptor dial and the regulator dial are turned completely OFF.

Step 2: Connect and plug in your electronic solenoid valve. Remember the golden rule: Power ON = CO2 Flowing.

Step 3: Slowly turn the dial on the SodaStream adaptor toward the ON direction until gas reaches the regulator (you will hear a brief “pop” sound). Leave the adaptor dial right there; no further adjustment on this part is needed.

Step 4: Slowly turn the regulator dial to increase your CO2 output to your desired bubbles-per-second. The pressure takes about 5–10 minutes to fully stabilize.

How to Automate Your CO2 Schedule:

Plants only consume CO2 when the lights are on. To prevent stressing your fish at night, you should automate your system:

Option A (Standard Timer Switch):

Plug the solenoid power adapter into a mechanical or digital wall timer. Set it to turn on 1 hour before your aquarium lights turn on, and off 1 hour before the lights turn off. (Or to turn ON/OFF same time as your light).

Option B (App Control):

Use an inline app-controlled timer module. Connect the module between your power source and the solenoid, and program your schedule via the Chihiros app.

Aquarium CO2 System Comparison Table

High-Tech Setups: The chart below assumes medium-to-high plant density and high lighting requiring a standard 30 ppm saturation.
Low-Tech Setups: Systems with lower lighting and slower plant growth require less CO2 injection. Lowering your dosage for these tanks will drastically improve the lifespan of your CO2 cylinders or cartridges!

Tank Size	Recommended Dosage (Bubbles/Sec)	Recommended CO2 System	Estimated Lifespan
30L & Below	1 bubble every 2–3 sec	74g Disposable Cartridge	2–3 Months
30L – 60L	1 bubble every 1–2 sec	74g Disposable Cartridge	1–2 Months
60L – 80L	1 – 1.5 bps	SodaStream Kit	3.5 – 5.5 Months
100L – 130L	1.5 – 2 bps	SodaStream Kit	2.5 – 3.5 Months
150L – 180L	2 – 2.5 bps	SodaStream Kit	2 – 2.5 Months
150L – 180L	2 – 2.5 bps	3.5kg Cylinder (Recommended)	~2 Years (1.8–2.2 years)
200L – 250L	2.5 – 3.5 bps	SodaStream Kit	1.2 – 2 Months
200L – 250L	2.5 – 3.5 bps	3.5kg Cylinder (Recommended)	~1.5 Years (1.3–1.8 years)
300L – 350L	4 – 5 bps	3.5kg Cylinder	11 – 14 Months
