Aquarium CO2 Diffuser for Planted Tanks, Ceramic Nano-Mist In-Tank Design in Two Tank Sizes

Give a planted aquarium a finer, more efficient CO2 supply using this in-tank diffuser. Its porous ceramic membrane turns passing CO2 into streams of tiny bubbles, increasing their surface area so the gas dissolves more readily into the water.

Choose the model that matches your aquarium volume: Small for tanks below 65G (250L), or Large for tanks above 65G (250L). The brown body blends into an aquascape, while two suction cups provide solid positioning on the aquarium glass.

Key Features

• Fine nano mist: The improved ceramic membrane produces streams of tiny CO2 bubbles, increasing contact area so carbon dioxide dissolves more readily in the water.
• More efficient CO2 use: The diffuser optimises incoming CO2 for plant absorption and reduces waste, making each supply more useful to the planted aquarium.
• Tank-specific sizing: Separate versions suit aquariums below or above 65G (250L), allowing selection according to tank volume.
• Natural-looking placement: Brown coloration blends into the aquascape, keeping attention on the planted layout.
• Stable glass mounting: Two high-quality suction cups provide solid positioning, helping the diffuser remain where it is placed.
