Easy Water Refill CO2 Bubble Counter with Check Valve and Water Adder for Planted Aquarium CO2 Regulator (Thread Connection)

Easy Water Refill CO2 Bubble Counter with Check Valve for Planted Aquarium CO2 Regulator

As we all know, most plants in planted tanks are emergent or semi-aquatic plants, and their ability to absorb HCO3- in submerged environments is relatively poor. Therefore, precise addition of gaseous CO2 to provide sufficient carbon sources is particularly important. The bubble counter offers significant advantages in precise addition and measurement. 1. Built-in Check Valve: The aluminum alloy bubble counter comes with a built-in check valve, eliminating the need for a separate device. This ensures there is no backflow caused by pressure differences, preventing leaks and equipment damage. 2. High Compatibility: Regardless of the type of CO2 generation method or CO2 diffuser structure, this aluminum alloy bubble counter can fully adapt and integrate into the entire CO2 system. 3. Stable and Reliable Material: Made from corrosion-resistant and sturdy aluminum alloy, this bubble counter is much more reliable than plastic or glass bubble counters, and even those with integrated bubble counter diffusers. It is virtually unbreakable and can be used stably over a long period. Stability is LINLAN's top recommendation for CO2 systems. 4. Secure Connection: The bubble counter features a locking mechanism at the hose connection point, ensuring a firm grip on the hose with no risk of detachment. Bubble counters without a locking mechanism are not reliable. What Makes the LINLAN Water-Refillable Bubble Counter Stand Out? In most CO2 generation methods, the produced CO2 is very dry. As the bubbles pass through the bubble counter, the CO2 gradually depletes the water inside, eventually rendering the bubble counting function ineffective. This is especially common in systems with high CO2 dosing. Disassembling the bubble counter and refilling it with water can be frustrating. The LINLAN water-refillable bubble counter solves this issue by allowing you to add water directly through a small hole using the included syringe. You don’t need to turn off the CO2 generator, and the refill can be completed in just 5 seconds. - Reduce your maintenance time and spend more time enjoying your aquarium! -

Key Features

• ✅ ?Easy Water Refill Function?Are you always annoyed by the lack of water in the bubble counter, but it is always very difficult to remove the bubble counter? With the LINLAN water-fillable bubble counter, you can directly add water from the small hole without disassembly, simplifying the operation.
• ✅ ?Includes Water Injector?With the water injector, you don't need to turn off the CO2 when adding water. Simply align the injector with the small hole on the bubble counter, ensure a tight connection with a little force, and push the water into the counter to refill it.
• ✅ ?Check Valve?The bubble counter has a built-in check valve. In some cases, there may be a pressure difference in the air pipe, and the check valve can prevent water from flowing back, thereby protecting the equipment.
• ✅ ?High-Quality Materials?The metal part is made of aluminum alloy, the hand-tightened part has threads to prevent slipping, and the middle part is made of durable PC (bullet-proof glass) material, suitable for various aquarium environments.
• ✅ ?Compatible Size?The bubble counter is compatible with 4/6 mm (3/16 inch inner diameter) CO2 tubes. The thread connection type fits M10x1 male thread connectors.
