UP Aqua D-531 Nano CO2 Atomizer

Simple refinement effect, allowing carbon dioxide to dissolve in water for water plants to absorb and utilize!
Curved hook design will not fold into the trachea.

The UP Aqua D-531 Nano CO2 Atomizer in a Planted Tank

This compact atomizer breaks your incoming CO2 into an ultra-fine mist so more of the gas dissolves before it reaches the surface, which means better plant uptake and less wasted gas than a coarse ceramic diffuser. The small body and curved hook design suit the nano and low-iron tanks that fit neatly into HDB and condo living rooms, and the hook keeps the tubing from kinking and choking the flow where it bends over the rim.

Atomizers like this generally need a little more working pressure to push gas through the fine membrane, so we suggest pairing it with a regulator that can supply steady pressure rather than a low-output paintball setup. In our warm 27-29C tanks where oxygen sits lower, we recommend running CO2 on a timer that shuts off before lights-out and watching livestock for any sign of stress, building the dose up gradually rather than all at once.
