I emptied and refilled the system to ensure it wasn't just out of gas, and I confirmed there are no leaks. Despite this, it still won't release any CO2. ## Features - [Precision Control Like Pro Regulator] -- No more guessing or inconsistent bubbles. Our precision needle valve lets you dial in the exact CO₂ flow with surgical accuracy. Paired with a water-injectable bubble counter, you can paired with the fine tuning valve to adjust the size and exit speed of bubbles without shutting down. Keep co2 levels stable for growing plants - [Dual Safety Lock] -- Our aquarium Co2 system features a 35KG auto-pressure relief valve that releases excess pressure automatically, plus a 12V waterproof solenoid valve that eliminates leakage risks. The main shut-off valve gives you manual control in emergencies. Whether it's in your living room or bedroom, you'll have total peace of mind - [Thicker 304 Stainless Steel] -- Our aquarium Co2 bottle is made from premium 1.2mm SUS304 stainless steel—20% thicker than standard tanks—making it durable, corrosion-resistant, and built to handle high pressure.The upgraded external thread design improves sealing, prevents leaks and blockages, and fits more raw material without residue - [Low-Cost Running] -- Our Co2 generator system runs on citric acid, baking soda, and water—all available at any supermarket for pennies. One fill lasts up to 45 days,so you can spend more time enjoying your aquascape and less time refilling. When the gas runs out, just reload - [Complete Co2 Aquarium Kit] -- We provide everything you need: regulator, filter, bubble counter, solenoid valve, atomizer, check valve, tubing, tools, and more.

You can judge based on the pressure gauge. When the pressure gauge is stable and the reading no longer rises, it means the reaction is complete. **Q: What should I do if the auto-pressure relief valve activates (at 35KG)?** A: Immediately turn off the main valve to halt the reaction. Check for blockages in tubing or the atomizer, and ensure you’re not overfilling the reactor with citric acid/baking soda. **Q: Can I add water to the bubble counter without shutting off the CO2 system?** A: Yes! The upgraded water-injectable bubble counter allows you to use the syringe to add water directly through the port while the system is running. No need to disconnect or stop CO2 flow. **Q: What is the correct citric acid/baking soda ratio, and how long will a 200g mix last?** A: Use a 1:1 ratio (200g each). At 1 bubble/second for 8 hours daily, it lasts ~45 days. For 24-hour use, expect ~15 days. Adjust using the fine-tuning valve to avoid waste and maintain stable CO2 levels. **Q: Can I open the steel cylinder before the pressure gauge returns to zero?** A: NO. After all the reaction gas in the cylinder is used up (i.e. the pressure gauge is reset to zero), adjust the micro adjustment valve to release the residual gas, and then open the cylinder valve for cleaning or re adding raw materials. ## Customer Reviews ### ⭐⭐⭐⭐⭐ use with uv light tank will stay clear *by R***. on February 26, 2026* works great has been running for over three months for six hrs a day on timer meter still shows high in green area ### ⭐⭐⭐ Good product, be better if it lasted longer *by O***N on February 19, 2026* It worked perfectly at first, and I had no issues until about a week ago when it suddenly stopped releasing CO2. I emptied and refilled the system to ensure it wasn't just out of gas, and I confirmed there are no leaks. Despite this, it still won't release any CO2. ### ⭐⭐⭐⭐ Solenoid valve not working unless you take it apart and then assemble again *by A***X on May 4, 2025* The tank is quite good and it works nicely (so far, less than a week from the first launch). However, its solenoid valve doesn’t do anything at all: whether or not it is on (the green indicator LED on), the gas is bubbling with the same rate. UPDATE: after I had disassembled the valve (found a pice of advice on a specialized forum), stared at its guts menacingly and then assembled it again, it changed its mind and started to work. I am not sure whether it was a stuck spring or my threatening stare, but… so far so good. --- ## 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/products/679464978-baoshishan-2l-aquarium-co2-system-with-precision-regulator-external-thread](https://www.desertcart.co/products/679464978-baoshishan-2l-aquarium-co2-system-with-precision-regulator-external-thread) --- *Product available on Desertcart Colombia* *Store origin: CO* *Last updated: 2026-06-03*
