## Summary description

Aqua Nova glass CO2 diffuser TN-44712 is a transparent aquarium accessory with a 28 mm connection designed to efficiently dissolve CO2 into aquarium water. Made of glass, it produces fine bubbles for improved gas exchange and plant uptake, suitable for planted tanks and CO2 injection systems. Ideal for hobbyists seeking precise CO2 distribution and stable oxygenation.

## Long description

The Aqua Nova CO2 Diffuser TN-44712 is a transparent glass diffuser designed for aquarium CO2 systems with a 28 mm connection. Made from glass, the unit produces a fine bubble pattern that helps dissolve CO2 into water efficiently, improving gas exchange and plant uptake in planted aquaria. The clear design allows unobtrusive placement inside the tank and enables easy observation of bubble generation and diffuser condition.
Advantages
The glass construction resists corrosion and maintains visual clarity over time, while the fine ceramic or membrane element ensures small, consistent bubbles to increase CO2 dissolution. Its 28 mm connection provides compatibility with larger tubing and certain inline setups. The transparent body minimizes visual impact in the aquarium and allows users to monitor performance without removal.
Suitable for
 Planted freshwater aquariums requiring CO2 injection for plant growth
 Aquarium systems with a 28 mm tubing or connection point
 Hobbyists seeking a discreet, glass diffuser with visible bubble output
 Setups where efficient CO2 dissolution and small bubble size are desired
When it may not be suitable
This glass diffuser may not be appropriate for very small aquariums where a large 28 mm connection is incompatible or where compact plastic fittings are preferred. It is also not intended as a replacement for full reactors in large-volume or high-demand CO2 systems that require higher dissolution capacity or external reactors.
Key specifications
 Material: transparent glass
 Connection diameter: 28 mm
 Function: produces fine CO2 bubbles for dissolution into aquarium water
 Intended use: internal in-tank CO2 diffusion for planted aquaria
How to use
Install the diffuser inline or directly inside the aquarium at a lower flow area to maximize contact time between bubbles and water. Connect tubing or a suitable adapter to the 28 mm connection, ensuring a secure and airtight fit. Position the diffuser near circulation zones or below aquascape features so that bubbles are dispersed through the water column; adjust CO2 flow rate on your regulator to achieve steady fine bubble emission. Periodically inspect the glass surface and the ceramic or membrane element for clogging and clean gently with appropriate methods to avoid damage.
What to consider before purchase
 Confirm compatibility of the 28 mm connection with your tubing or adapter
 Check that glass material and diffuser size suit the aquarium layout and circulation
 Determine whether an in-tank diffuser meets your CO2 dosing requirements versus an external reactor
Usage recommendations
For best results use the diffuser with a stable CO2 regulator and bubble counter, place it lower in the tank or near a filter outflow to increase dissolution, and perform gentle cleaning when bubble output decreases to maintain consistent performance.
