The “Oxygenation & Aeration” category gathers tools and devices designed to enhance water oxygen levels and circulation in aquariums. Air pumps, diffusers, Oxydator systems or aerators ensure sufficient dissolved oxygen, promote gas exchange (O₂ / CO₂), stabilize water quality, and prevent hypoxia — even during heatwaves or with high stocking levels.

These devices are especially useful in densely populated tanks, shrimp or sensitive invertebrate setups, or during critical periods (heat, startup, medication…). Good aeration supports the health of fish, shrimp, invertebrates and plants, improves biological filtration, distributes nutrients, and reduces harmful waste accumulation.
