I don’t use it anymore because I upgraded to a full CO2 tank setup (which is way less maintenance long-term), but this kit was such a good introduction into CO2 for me. What I really liked is that it comes with basically everything you need to get started, which made the whole process way less intimidating. When you’re new to CO2, it can feel really confusing (like figuring out bubble rates, diffusion, etc.), and this kit helped me actually understand how everything works. The instructions were clear enough, and as long as you set it up correctly, it does work well. It comes with tubing and a diffuser (no CO2 indicator, but that wasn’t a big deal for me). The quality of the materials is actually pretty solid too (no leaks if done properly!) I still use some of the Criscea parts in my current setup like the bubble counter, tubing, inline checker, and diffuser, and they’ve all held up for almost 6 months now with no issues. So even after upgrading, parts of this kit are still useful, which I appreciate. The main downside (and the reason I switched) is just the maintenance that comes with DIY CO2 systems. It’s not bad, but it does require more attention compared to a standard CO2 tank. Once I got more into aquascaping, I just wanted something more consistent and lower effort. Overall, I’d definitely recommend this if you have a smaller tank, are on a budget, or just want to learn CO2 before committing to a full system. It’s also a really good learning tool (honestly could even be fun for a kid or beginner who wants to understand how planted tanks work). Great cheap starter kit that actually helped me level up my setup. Review: Really solid set up for the money - So far ao good been two weeks now after getting the system, easy startup and tuning. I have this on a kasa smart outlet set to a timer and has run with zero issues. Would recommend using glycerin in the bubble counter vs water. Two reasons for this, you dont have to top the glycerin off as it does not evaporate, and two its easier to count your bubbles and fine tune it, added bonus it looks cool. Set up is straight forward, mixing easy just layer material and pre cool a 2 liter jug of water the night before and add some ice 1 hour before adding and keep it in the fridge. 2 weeks at 1.75-2 bubbles per second on a 20 gallon planted tank seems to be the sweet spot considering my plant load everything grows at a marked accelerated rate. All components are solid, tank is of good quality and safety vave ( blow out ) is a nice feature. Good set up that won't break the bank to up your game to a "high tech" tank. Very happy with this system. ## Features - 【Small Body, Big Power】Thickened cylinder, bottle body is made of thickened SUS304 stainless steel, gas storage capacity equals 4L cylinder!

Also how far can the tank be from the CO2 canister?** A: The length of the CO2 tubing is 2 meters. There is no requirement distance between the CO2 cylinder and the plant tank, but is should not be so far, because too long of the CO2 tubing will need more working pressure to make the diffuser work. **Q: question regarding citric acid and baking soda, is there special one you have to purchase or can you use any citric acid and baking soda?** A: Food grade baking soda and citric acid are recommended. Experimental grade raw materials are expensive and not cost-effective. Industrial grade raw materials produce impure gas from the reaction. **Q: I do have question regarding the installation, not sure what it means by wait 10 hours. Do I setup everything as if I was going to run but wait 10 hrs** A: After adding the ingredients and screwing on the CO2 regulator, wait 10 hours to allow the ingredients to fully react. Then proceed to the next connection step. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great starter CO2 kit, but I eventually upgraded *by J***A on April 13, 2026* I'd rate this 5/5 for what it is.

Very happy with this system. ### ⭐ Buy your own accessories *by K***2 on September 18, 2025* The tank and concept are great, however the regulator and accessories are disasters. The bubbles per second you get from the regulator vary by almost 50% left and right of what you set it to at any given moment. I think I'll be turning the co2 system off while on vacation. The co2 resistant tubing is resistant to everything i try to do. It's a tight spiral slinky despite all of my efforts. I filled and soaked the tubing in hot tap water and tried to stretch it, but it just coils back up like a spring. Speaking of soaking, for some reason there's instructions to disassemble the relay switch and soak several of its parts in alcohol for an undisclosed amount of time. It gives you nice tools to take it apart, but putting it back together is a nightmare of bloody finger tips. The system seems to work, but I'm real nervous it's gonna kill everything in my tank. (Update and added a video) I've changed my review to 1 star. The shut off relay broke the first night I left it alone. I woke up to the ph indicator saying there was an issue in my fish tank and when I checked things out I found the relay wouldn't shut the co2 off even when unplugged. ## Frequently Bought Together - Clscea Aquarium CO2 Generator Kit Double Pressurization Enhanced Version, G700S - Clscea Aquarium CO2 Raw Materials Citric Acid and Baking Soda - Clscea Aquarium CO2 Drop Checker CO2 Indicator (Glass Checker+15ml) --- ## 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.co.uk/products/333675030-aquarium-co2-generator-kit-double-pressurization-enhanced-version-g700s](https://www.desertcart.co.uk/products/333675030-aquarium-co2-generator-kit-double-pressurization-enhanced-version-g700s) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-17*
