Guess what? It works for yeast too. One caveat with yeast vs. citric acid... If you let the pressure build up on yeast, the mixture's CO2 content will increase and the pH will drop. You can potentially shut down the fermentation through pH drop and CO2 toxicity, although the yeast will likely just go dormant vs. dying. What this means is that shutting off the white on/off valve to build up pressure is unlikely to produce enough pressure that your gauge will show anything at all. Even with this, you can build up enough pressure inside the generator bottle that you can use the regulator. I use a Paffrath bell to regulate the amount of CO2 in surface contact with my aquarium's water. This is probably a better idea than using a CO2 fine-mist diffuser for yeast, since you have less control over production volume and it's better to waste a little bit of CO2 than to overdose your tank. What I like: - Tight seals on both bottle caps and hose fittings. - I like the high-quality appearance. - No messing with silicone and adaptor fittings, this thing just goes together. - Use whatever size bottles make sense as long as they fit standard-sized caps. I use a 2 liter for the yeast generator and a 1 liter for the bubble counter. - No durability issues so far with any hose or fitting failures. - I can position the whole assembly behind my micro-tank without worrying about appearance. Review: Really good on a budget - The kit works great only bad thing is the valve that comes with the system, if you let your pressures get above 1.5~ adjusting bubble rate becomes a real challenge. I have come home to dangerously high co2 levels 2 times because of the valve although I shouldn't have left the system generating co2 while I was gone so you could attribute that to user error. Great bang for your buck and my plants are thriving thanks to this kit. ## Features - The DIY CO2 Kit provides an excellent method of deploying the citric acid / baking soda solution to generate CO2 for plants' growing in the aquarium. Easy to operate and designed for low cost planted tank use. - Highlight: Much easier and safer to control. A quick reaction test tube simplifies the procedure and achieves a fast reaction. The unique design of acid absorbing ball makes it more convenient to control acid consumption. Besides, there is a simple pressure relief valve under the pressure gauge. - Durable: Our tubing is highly resistant to pressure, and the tubing between the two caps is even acid- and hydrolysis-resistant. ABS engineering plastic caps with professional stable structural design ensure that they are non-deformable, anti-wear and anti-aging. - Our CO2 Generator Kit includes most accessories. You only need to prepare yourself: 2 additional carbonated beverage bottles (preferably for 2L), e.g. Coke or Sprite; reaction materials: baking soda and citric acid; check valve and CO2 diffuser. - * Tips: 1. The needle valve is only used to adjust the output volume, It only need to be adjusted once. Daily switching can be controlled by the white on/off valve. The reason for this is to ensures the gas output is stable. 2. DO NOT use bottles other than carbonated beverage bottles. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08XZ4T67L | | Best Sellers Rank | #35,910 in Pet Supplies ( See Top 100 in Pet Supplies ) #72 in Aquarium Test Kits | | Brand | Clscea | | Brand Name | Clscea | | Customer Reviews | 4.2 out of 5 stars 167 Reviews | | Item Form | Powder | | Item Weight | 200 Grams | | Liquid Volume | 2 Liters, 200 Milliliters | | Manufacturer | Clscea | | Target Species | Aquatic Plants | | Unit Count | 1.00 Count | ## Product Details - **Brand:** Clscea - **Item Form:** Powder - **Item Weight:** 200 Grams - **Liquid Volume:** 2 Liters, 200 Milliliters - **Unit Count:** 1.00 Count ## Images ![Aquarium DIY CO2 Generator System Kit, G200 - Image 1](https://m.media-amazon.com/images/I/51mdYFzDPLL.jpg) ## Available Options This product comes in different **Color** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great for yeast *by D***B on October 10, 2025* Ok, this CO2 Generator System kit is intended for a citric acid setup.

However the needle valve has stopped working I'm not sure if it's dirty or something else, I'm assuming it's a known problem and that's why the new version has a metal one. But either way mine has a problem and that's why I only give it 4 stars. Otherwise all of the other parts seem to be good quality and haven't given me any problem. ## Frequently Bought Together - Clscea G200 Aquarium DIY CO2 Generator System Kit - Clscea Aquarium Glass CO2 Diffuser Atomizer with U Tube Check Valve Suction Cup Premium Version - Fluval 88g-CO2 Bubble Counter - 3.1 Ounces --- ## 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.be/products/336201725-aquarium-diy-co2-generator-system-kit-g200](https://www.desertcart.be/products/336201725-aquarium-diy-co2-generator-system-kit-g200) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-07-03*
