lime cube for CO₂

This linden wood airstone is for aquarists who want to add gas to their tank water through a standard airline hose. It is listed in the CO2 systems category, and the supplier describes its function as dissolving oxygen in water by producing fine micro-bubbles.

Why it matters

• The porous wooden body releases gas as micro-bubbles, which are the mechanism the supplier cites for dissolving gas into the water.
• A connector at one end fits a standard airline hose, so no special fittings are needed to connect it to a compatible supply line.
• Made of linden wood, a natural material, rather than a synthetic diffuser body.
• Light, at 0.02 kg, so it is easy to position in the tank.

What it works with

The listing does not specify tank volume or compatible gas type beyond the CO2 systems category, so check the requirements of your own setup before purchase.
