Description

Thicker and last longer! Fzone's DIY CO2 bottles last longer and are thicker than average! With a strong interior wall that can hold more raw materials, our bottles are made of 1.5mm thick SUS304 graded stainless steel, 25% thicker than competitors. The Fzone co2 kit aquarium can withstand a max 80kg/cm2 pressure and generates CO2 gas for 1 month at 1bps for 8 hours a day when filled with 300-400g raw materials. Get a longer-lasting and more efficient CO2 solution with Fzone!

Professional DIY kit -- A complete system in 2.5L size bottle, that includes SUS304 stainless bottle, regulator, precision needle valve, and easily adjustable bubble counter. Safety valve will open automatically when the inside pressure exceeds the safety threshold.

High precision--Needle valve with bubble counter. Aquarium specific needle valve provides accurate fine-tuning. Steady 1 bps is achievable. Bubble counter with check valve built-in. It stops water from back flowing into your CO2 tank (protects your CO2 tanks from rust and corrosion)

12V DC Instead of AC Power: having the solenoid on a timer, you can specify when you want CO2 injection on and for how long

Attentions: the required powders to generate CO2 gas are not included; you will need purchase the citric acid and sodium bicarbonate powders separately.

Common questions about buying open-box and refurbished.

Why buy refurbished or open-box?
Refurbished and open-box products offer the same performance as new at a fraction of the price. You're already saving $23 on this listing. They've been inspected, tested, and are ready to use — the only difference is the price tag. Buying refurbished also reduces electronic waste, extending product life cycles and keeping functional devices out of landfills.
What's the difference between open-box and refurbished?
Open-box products are customer returns that have been inspected and confirmed functional. They may show little to no use — often the item was returned simply because the buyer changed their mind. Refurbished products have been professionally repaired or restored by technicians, tested to meet or exceed manufacturer specifications, and sometimes come with a warranty. Both are a smart alternative to buying new.
Why use OpenBoxFox?
Finding refurbished deals is time-consuming — you'd have to check Amazon Warehouse, Reebelo, Dyson Outlet, and others separately for FZONE products. OpenBoxFox aggregates these listings in one place, so you can compare and find the best deal without the legwork. We update pricing daily so you always see current availability and real savings.
Is it safe to buy refurbished?
Yes. Products listed on OpenBoxFox come from established retailers like Amazon, Reebelo, and Dyson — not unknown third-party sellers. Each retailer has buyer protection policies, return windows, and in some cases warranties. You get the price advantage of used goods with the purchase security of a known retailer.
