## Description

desertcart.com : Upgraded 2L/5L Aquarium CO2 Generator System with Timer-Enabled Motor Valve, Upgrade CO2 System Kit with Quick-Release Structure for Aquarium Plants Tanks (5L) : Pet Supplies

Review: Product is great - instructions... not so much - This is the best "refill at home" kit available right now. It's the only one with the motor valve/timer, quick disconnect fittings and the new threaded tank design. I've had this installed and running for a bit now and I have no problems with it functionally. There are two areas of improvement the company could make. First, is the tubing included needs to be coiled into a circle for shipping. They have it folded and the tubing I received was full of creases. I ended up ordering some CO2 resistant black tubing from another seller. The other problem is Hygger needs to hire a proper technical writer and give much better instructions with the product. As of right now, this product is not listed on Hygger's website - at all. The instructions included are absolutely horrible. You will find better instructions on this desertcart listing than anywhere else. It doesn't take a rocket surgeon to figure a lot of this out, but people new to these things may have some difficulties. Even with the old model this replaces, there are youtube videos where the people installing it are completely lost trying to assemble/set it up looking at the instructions. Eventually the figure it out, but this could be avoided easily by Hygger. Also, people should be using 600g baking soda, 462g citric acid and 900ml water. This (and every other 5L CO2 setup) recommends 600g baking soda, 600g citric acid. That is not the correct formula and 462g of citric acid is all that is used in the reaction, the rest is waste. And as citric acid is much more expensive than baking soda, you can also reduce your operating costs by using the lesser amount. It would be nice if Hygger and the rest of these updated their instructions/stickers to reflect this. The timer was easy to program, but I do recommend people initially putting it into manual mode to get it going. You will hear the motor open/close when activating it. Once you get it working in manual mode and get your desired bubbles/second set, then program your start/stop times in the timer and activate auto mode. The included diffuser is very good as far as a fine mist of micro-bubbles. I'd recommend purchasing a bigger funnel for filling, the included one is a bit on the small side IMO. All in all, this is a great unit for people who can't or don't want to get CO2 from local sources and want to be more self sufficient in making their own CO2. The cheapest baking soda/citric acid is found on desertcart in 50lb buckets.
Review: Seliod does not stop the CO2 - Had some issues with the seliod at after a few days of using it. After emailing Hygger we had it working correctly after a few steps.

## Features

- For first-time use, after setting the automatic mode, if the system is running, please switch to manual mode to turn it off first, then turn it back on. After turning it on, switch back to automatic mode to activate the built-in program and ensure proper operation. Just follow the above steps to set it up once, and you can use it normally afterwards. We are currently optimizing and adapting the timer's built-in program for future direct use.Thanks for your understand and support!
- Things to Note Before Purchase --(1)The motorized valve may make a soft sound when turning on/off — this is normal; (2)Soak the diffuser in your aquarium for 24 hours before use. If bubbles aren't released right away, wait briefly due to low initial air pressure. If problems continue, check tube connections for leaks; (3)The motorized valve is not waterproof; (4) Baking soda and citric acid need to be purchased separately.
- Revolutionary Motor Valve Technology -- Upgrade your aquarium setup with our advanced CO2 generator system featuring a state-of-the-art motor valve. Unlike traditional solenoid valves, our motor valve allows you to set precise timers, ensuring consistent CO2 injection at your desired intervals. This exclusive feature sets our CO2 system apart from competitors, providing unparalleled control for optimal plant growth.
- Quick-Release Structure for Hassle-Free Installation -- Experience the convenience of our CO2 aquarium kit's quick-release design. The bubble counter, valve, and air tube all feature a snap-in structure, replacing the old screw-on design. Installation and disassembly are now a breeze, saving you time and effort.
- Heavy-Duty & Durable Build -- Our 2L CO2 bottles are crafted from 1.2mm premium SUS304 stainless steel, while the 5L ones are made of 1.5mm premium SUS304 stainless steel, both being 20% thicker than standard tanks. These robust bottles are far superior to plastic alternatives, offering enhanced durability, stability, safety, and high-pressure resistance, ensuring long-lasting performance.
- Comprehensive Safety Features -- Your safety is our priority. An automatic pressure relief valve activates when CO2 pressure exceeds 30-40bar, safeguarding your aquarium from overpressure risks. With careful design and quality materials, we've minimized potential leakage points, ensuring a secure operation environment for your aquarium and its inhabitants.
- All-In-One DIY Kit -- Our CO2 generator for aquarium plants comes as a complete kit. It includes a CO2 cylinder, hose, suction cups, bubble counter, CO2 diffuser, and the innovative motor valve. Simply add baking soda, citric acid, and water to the cylinder, close the valve, connect the accessories, and start providing your aquatic plants with the CO2 they need.
