Review: FZone 2.5L CO2 Generator - After carrying out a lot of research I decided this system would be the best bang for bucks system for my 120L system. I've been running the generator for 3 months now and I'm really impressed with it. It was easy to set up and the raw ingredients are cheap and easily purchased from desertcart. The powders are added and then the water is added very slowly with the bottle at a 45 degree angle. pouring it slowly slows down the chemical reaction and stops you wasting gas as you screw the regulator on to the bottle. I was getting 2 weeks of CO2 from one charge and when I added a CO2 reactor that figure went up to almost 4 weeks. 4 weeks of CO2 from 200g of acetic and 260g of Bi Carbonate is in my opinion amazing. The regulator is easy to adjust and the solenoid valve works as it should. The kit itself contains everything you need, except the raw materials and a drop checker. These can be picked up cheaply from desertcart. CO2 has made a big difference to my plants and algae growth is virtually zero now. This kit has been the best piece of kit I have bought for my aquarium in a long time. If you want to add CO2 to your system this is a great straight out of the box solution.
Review: Quality system thats easy to setup - This is excellent. I was wary of complicated systems and setups but on trying this one its an easy mix of citric acid and bicarb and Ive had over a month of CO2 so far. Easy to set up and easy to adjust the bubbles per second. Has made a visible difference to my plants. Green and lush and visibly improved growth. You can put it on a timer easily with the included solenoid. The bottle is top quality too. Excellent set up and super glad Ive added this system to my tank.

## Features

- Professional DIY Kit. A complete system in 2.5L 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
- One-year Warranty：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.

### ⭐⭐⭐⭐ Easy to set up with help of YouTube
*by M***H on 18 February 2024*

Great product, easy to use just the manual was really poor. It never mentioned the solenoid and how to use it, I had to use YouTube and the bent glass but that sits on the tank where the tubes connect is really fragile and not very well made, I broke mine first day. Other than that it’s a great product my plants have doubled in growth.
