For this family listing we selected the Fzone Desktop Aquarium Mini CO2 System, a representative compact CO2 kit for small and nano planted tanks. It uses a high-strength aluminum-alloy mini regulator compatible with disposable 45g CO2 cartridges (5/8" thread, with a 3/8" adapter included) and provides stable CO2 output with quick-connect tubing and precision sealing. A single 45g cartridge lasts up to 50 days at 1 bubble per second running 8 hours daily.

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?+
Add items in the bundle builder: 2+ items saves 5%, 3+ saves 8%, 4+ saves 12%, and 5+ saves 15% off the whole system, applied at checkout.
