The Chihiros Mini CO2 Regulator Kit with Solenoid is an ultra-compact, high-precision carbon dioxide delivery system tailored specifically for nano and small planted aquariums. It is designed to fit desktop aquariums up to roughly 30 cm or 20-cube tanks. This provides a space-saving and highly functional alternative to bulky full-sized pressurised systems.

Please note a common point of confusion: while retailers often sell a base manual version of the mini kit, the premium combo bundle explicitly packs the standalone Chihiros Solenoid Valve & Power Supply alongside the core regulator setup. With this bundle, you get automated control over your gas scheduling.

Included in the Box:

The standard full-kit bundle generally features:

• Mini CO2 Regulator: A lightweight, sleek aluminium body with an integrated pressure gauge for clear monitoring.
• Chihiros Solenoid Valve & 12V Power Adapter: A 2.8W low-power, minimal-heat electronic valve that allows automated on/off functionality when plugged into a traditional wall timer.
• Threaded 16g CO2 Cartridges (x3): Disposable cylinders (UNF 3/8 standard threading) that easily screw directly into the base of the regulator.
• Nano CO2 Diffuser: Features a fine ceramic disc to break down gas into microscopic bubbles for optimal water dissolution.
• Premium Soft Air Hose: 1 meter of pressure-rated clear silicone tubing.
• U-Clip hanger (8mm): Keeps the tubing cleanly pinned over the aquarium rim without kinks.

Key Benefits:

• Automated Safety: By pairing the inline solenoid with a lighting timer, you can stop gas injection at night when plants aren’t undergoing photosynthesis. This prevents toxic gas buildup, protecting your fish and shrimp from suffocation.
• Impressive Gas Efficiency: In baseline tests running at a conservative dosing rate of 1 bubble every 5 seconds for roughly 8 hours a day, a single 16g cartridge can last up to 35 days.
• Sleek Aesthetics: The tiny profile eliminates industrial-looking heavy cylinders, keeping small spaces and desktop home offices clutter-free.
• App-Upgradable: The entire assembly can be integrated with the optional Chihiros Bluetooth Solenoid Controller, letting you control exact operating hours wirelessly via the My Chihiros smartphone app.

*Please note, a bubble counter can be added to this kit. Ask us how or shop for one in our store or online
