AquaLabs Injectable Bubble Counter

An easier way to keep your bubble rate visible.

Bubble counter water evaporates over time, and topping it up usually means shutting off the gas and unthreading the counter from your regulator. The AquaLabs Injectable Bubble Counter adds a sealed refill port so you can skip that entirely.

Draw up water with the included syringe, inject it straight through the port, and your bubble rate is clear and countable again in seconds. No tools, no disassembly, no interrupting your CO2 supply.

Threads directly onto your regulator for a compact, leak-free fit. A simple upgrade for anyone who wants their CO2 dosing visible at a glance, all the time.

• Sealed refill port with included syringe: top up in seconds
• No need to remove the counter or shut off your CO2
• Clear chamber for an accurate, easy-to-read bubble rate
• Attaches directly to the regulator
