Aquarium CO₂ Cylinder Refill

Description – CO₂ Cylinder Refill

Refilling a CO₂ cylinder for an aquarium consists of filling a rechargeable bottle with compressed carbon dioxide to ensure a continuous supply for the CO₂ injection system. This operation allows the same cylinder to be reused instead of buying a new one, making it more economical and environmentally friendly.

The refill is usually carried out in specialized shops (aquarium stores, paintball centers, breweries, or industrial gas suppliers). The cylinder must be certified and in good condition to be refilled.

During the refill, CO₂ is compressed into the cylinder at high pressure (often around 50–70 bar depending on conditions). Once filled, the bottle is simply reconnected to the regulator of the aquarium CO₂ system.

The refill ensures a constant supply of CO₂, essential for promoting photosynthesis, plant growth, and maintaining balance in a planted aquarium.
