Quick Carb Bong - Closed Loop Carbonation Kit

Say Goodbye to the "Shake and Pray" Method

Want to perfectly carbonate your beer, cider, or RTDs without waiting two weeks? Tired of gambling with the carbonation gods by cranking up the gas, shaking the heck out of your keg, and setting a million phone alarms to remind you to turn it down?

The Quick Carb Bong | Closed Loop Carbonation Kit delivers super-fast carbonation with absolutely none of the risk. Over-carbonated or under-carbonated beer is officially a thing of the past. With this high-efficiency keg carbonation pump kit, you can dial in your exact target CO2 and see a visible indicator of when the process is complete.

The Foolproof Carbonation Formula

Calculating your pressure is incredibly simple:

• Gas Injection Pressure: The final pressure you will set your CO2 regulator to.
• Wetting Pressure: The baseline pressure required to push gas through the pores of the stainless steel diffusion stone. (This stone averages around 4psi. You can easily test yours by submerging it in water and slowly raising the gas until you see the first stream of micro-bubbles).
• Desired Carbonation Pressure: Find your beer’s current temperature on a standard carbonation chart to see the exact PSI needed for your target volumes of CO2.

Example: Your beer temperature is 2°c and your desired CO2 volume is 2.6. Your chart says you need 11.2PSI of pressure.

Gas Injection Pressure = 4PSI (Wetting) + 11PSI (Desired)} = 15PSI

Step-by-Step System Setup

1. Assemble the Quick Carb Bong as shown in the pictures or watch this video here
2. Connect the liquid disconnect to your keg's liquid-out post. This line feeds directly into the intake of the Super Sucker Pump.
3. Route the pump's output to the side carbonation cap of the Quick Carb Bong.
4. Connect the remaining liquid line from the non-stone end of the Quick Carb Bong back to the gas post of your keg using the included gas disconnect.
5. Set your CO2 regulator to your calculated Gas Injection Pressure before connecting the gas line to the carbonation stone.
6. Turn on the pump! You will instantly see a stream of micro-bubbles entering the line.
7. Relax. Let the pump run until bubbles are no longer visible in the line. Your liquid is now perfectly balanced and fully carbonated. Pour yourself a fresh, crisp beer!

⚠️ Critical Pro-Tip for Freshness

Because this closed-loop system aggressively moves the liquid to maximize CO2 absorption, it is absolutely vital that your keg is 100% free of oxygen. Before transferring your brew, we recommend using the liquid displacement method:

• Fill your keg entirely to the brim with [StellarSan sanitizer solution].
• Use CO2 gas to push the sanitizer out into an empty bucket, leaving a keg full of pure, food-grade CO2.
• Perform a closed, pressurised transfer from your fermenter into the purged keg.
