How will the system run without one?** A: The solenoid will control the co2 output. When turn off the solenoid, there will not be co2 out from the generator. If without the solenoid, the co2 will keep output. **Q: How long do I have to wait before using the set up in my tank?** A: You can use it as soon as the needle is in the green. **Q: How can i replace the needle valve. Mine is broken alternating between full throttle or 0?** A: This isn’t a replacement part for the co2 generator it’s valve for a co2 tank. I recommend contacting the manufacturer. **Q: For a 4l co2 generator, should i put in 600-800 gram each of material a&b? also do i pour in 300ml water or more? i've read different opinions online.** A: I use 600 ml for the material each and 800 ml of water I freeze the water in try"s that make long round ice cubes the cube are made to put in water bottles ## Frequently Bought Together - Fzone 2.5 L Aquarium CO2 Generator System Carbon Dioxide Reactor Kit with Regulator and Needle Valve for Aquarium Plants Tanks - FZONE Aquatic CO2 Glass Drop Checker PH Momitor for Aquarium Plant Fish Tank Test CO2 Kit - Clscea Aquarium CO2 Raw Materials Citric Acid and Baking Soda --- ## 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.sg/products/605905846-fzone-2-5l-co2-aquarium-system-carbon-dioxide-reactor-kit](https://www.desertcart.sg/products/605905846-fzone-2-5l-co2-aquarium-system-carbon-dioxide-reactor-kit) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-09-20*
