## Description

FZONE 5.5L Aquarium CO2 Generator System Carbon Dioxide Reactor Kit with Regulator and Needle Valve for 600-800g Raw Material

## Features

- Professional DIY Kit: a complete system in 4L size bottle, that includes SUS304 stainless bottle, regulator, precision needle valve, and easy adjustable bubble counter
- Safe: the bottle body is made of 1.5mm thick SUS304 stainless steel (25% thicker than normal 1.2mm bottle); it can sustain pressure up to 80kg/cm2(or 1137 PSI); safety valve will open automatically when the inside pressure exceeds the safety threshold
- Needle Valve with Bubble Counter: high precision, 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 citric acid and sodium bicarbonate powders. Fzone will offer a one-year warranty, round-the-clock service, and you can reach out to us at any time for any product-related concerns.
