Frequently Asked Questions

Q: What thread size does this CO2 cylinder use, and what regulators are compatible?

A: The Dreamburgh CO2 cylinder features an M18×1.5 threaded valve port. This is a widely used standard thread size compatible with most aquarium CO2 regulators, soda carbonation valves, and other fittings designed for M18×1.5 connections. Always verify compatibility with your specific regulator before purchase.

Q: Is this CO2 tank safe for home aquarium use?

A: Yes. The cylinder is constructed from high-quality aluminum alloy with 6.3 mm thick walls, rated to 30 MPa (4500 PSI), and features an explosion-proof design. For aquarium use, it should always be connected via an appropriate pressure regulator and check valve to ensure controlled, safe CO2 delivery to your fish tank.

Q: Can I refill this CO2 cylinder?

A: Yes, the cylinder is designed to be refillable. It should be refilled only by qualified professionals using appropriate equipment and following local regulations for compressed gas cylinder handling and filling. Do not attempt to refill it with incompatible gases or without proper equipment.

Q: What capacity should I choose for my planted aquarium?

A: The right capacity depends on your tank size and CO2 consumption rate. Smaller tanks (under 20 gallons) may do well with the 0.25L or 0.3L option, while larger planted setups benefit from the 0.45L or 0.5L cylinder for longer intervals between refills. The 0.35L is a popular all-around choice for mid-size aquariums.
