This is a great little setup. I had a larger F-Zone reactor kit and this works just as good as the big guys. THe value for the money is amazing as you can get new cartridges for cheap. No noise to speak of, I added it to an inline diffuser and it's crushing it! after jus about a week my tank has perked up immensely, beautiful greens and looks like more root growth and spreading. Well made, super durable and seems to be super well made. If you want an easy solution for CO2 I would go with this all day long! --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/729865290-desktop-aquarium-co2-system-45g-co2-cartridge-5-8-3](https://www.desertcart.gr/products/729865290-desktop-aquarium-co2-system-45g-co2-cartridge-5-8-3) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-10-15*
