A complete planted-aquarium CO2 kit built around the CO2Art Pro-SE Series dual-stage regulator, the centerpiece of the system. The Pro-SE features an integrated 12V DC solenoid, dual gauges, a precision needle valve, a built-in bubble counter and check valve, and a dual-stage design that holds steady output pressure as cylinder pressure drops to prevent end-of-tank dump. Paired with a CO2 cylinder, an Aquario NEO ceramic diffuser for ultra-fine bubble diffusion, and a glass drop checker for monitoring CO2 saturation, it forms a full ready-to-run injection setup.

The questions our support inbox actually gets.
Does it ship quickly?+
Orders placed before 2 PM ET on a business day leave the same day. Tracking is emailed the moment the label prints.
What if it's the wrong fit for my tank?+
Return it. 30 days, no restocking fee, refund to the original payment method. Better: tell us your tank first and we'll spec the system for free — half of all returns are sizing problems.
Who handles the warranty?+
We do. Everything carries the manufacturer's warranty and we run the claim for you — one email to us instead of a ticket queue.
How does the bundle discount work?+
