The UNS Micro CO₂ Bubble Counter gives you a crystal-clear visual of exactly how much CO₂ is entering your aquarium so you can keep your plants happy and your livestock safe. Featuring an integrated check valve to stop water from backflowing into your sensitive equipment, it delivers total peace of mind alongside precise dosing feedback.
Note: For optimal bubble tracking, use a high-viscosity bubble counter fluid rather than water to prevent rapid evaporation.

1. How do I fill the bubble counter without taking it apart?
Simply remove the top sealing plug on the quick-fill port and use the included syringe to inject your bubble counter fluid or distilled water directly into the chamber.
2. Does this bubble counter require a separate check valve?
It features an integrated internal check valve to prevent back siphoning, though adding an additional inline check valve near your diffuser is always good practice for extra security.
3. Can I use plain water inside the bubble counter?
Yes, distilled water works well, though specialized high-viscosity bubble counter fluid is recommended as it slows rising bubbles for easier counting and will not evaporate over time.

"Came in great condition, also came with 10lbs of rocks yet the bubble counter was packaged well enough to not take damage. Functions just as it should!"
"Quality build, would be nice if the co2 fluid was in stock"
"Bubble Counter works well and is easy to fill. I had issues with my UNS manifold block (inconsistent flow rates) and replaced the original bubble counters with these. I think the check valves on the old bubble counters (at least one of them) was bad. Now the bubble counters are easy to fill and are consistent."
"I love the convenience of being able to fill this."
"Loved that it has a spring loaded check valve in it, huge step up from my POS fluval bubble counter on my fluval bio co2. Very high quality piece of equipment at a cheap price."
