Not necessarily. 8 hours is just a common time required for the reaction of raw materials to complete. 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. What should I do if the auto-pressure relief valve activates (at 35KG)? 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. Can I add water to the bubble counter without shutting off the CO2 system? 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. What is the correct citric acid/baking soda ratio, and how long will a 200g mix last? 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. Can I open the steel cylinder before the pressure gauge returns to zero? 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. From a humble workshop to industry leadership, we’ve spent a decade mastering one mission: delivering precision temperature control for every marine and freshwater aquarium. Whether you’re in desert regions or sweltering summer cities—tired of unreliable AC or messy ice bottle hacks—BAOSHISHAN provides the perfect fish tank chiller to keep your underwater world stable and thriving. ## Features - [Precision Control Like Pro Regulator] -- No more guessing or inconsistent bubbles.

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 on Reviewed in the United States 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.pl/products/679464978-baoshishan-2l-aquarium-co2-system-with-with-complete-accessories-external](https://www.desertcart.pl/products/679464978-baoshishan-2l-aquarium-co2-system-with-with-complete-accessories-external) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-08-14*
