Review: Súper bien
Review: It's a decent DIY solution that's much better than doing it yourself in a 2L bottle. Does it have its challenges? Absolutely. It's not like a typical CO2 regulator that is just filled up with gas that you pump into your diffuser. This uses baking soda and citric acid to generate CO2 and if done properly, is highly effective. But due to its design, you do still need to pay careful attention to your drop checker and the overall consistency of the CO2 output is dependent on a lot of other factors as well like temperature and how long it has left in its monthly cycle.

## Features

- Thread Variation for Hassle Free Use -- Our aquarium co2 system upgrades from internal thread to external thread to fit more raw materials without residue. At the same time, the sealing is enhanced to prevent gas from escaping danger and blocking, ensuring smooth operation. So you can focus on your aquarium
- Enhanced Safety with Dual Switch Valve -- New main valve switch gives you full control of the CO2 generator. Worried about gas leaks during reactions? Just close the main valve. In addition, an auto - pressure relief valve kicks in at 35KG. Double layer safety keeps your aquarium plants safe and gives you peace of mind
- Water Injectable Bubble Counter -- Our upgraded bubble counter lets you add water while aquarium co2 generator is running. No need to turn off the gas or remove the equipment. Paired with the fine tuning valve, adjust the size and exit speed of bubbles. Keep co2 levels stable for growing plants
- Durable Build -- Co2 generator for plants is made of 304 stainless steel, It's durable, stable, safe, and high pressure resistant. Can accommodate at once with a 200g capacity for both citric acid and baking soda, expect consistent CO2 for healthier, lusher plants
- Complete Co2 Aquarium Kit for Easy Setup -- We've got everything you need: cylinder, valve, 3-stage filter, bubble counter, solenoid valve, base, 2.7" stainless steel atomizer, check valve, 78.7" air tube, silicone funnel, snap-on suction sucker, syringe, and spare sealing rings. Saves you the hassle of scouring multiple stores for individual component purchases
- Tips for All Users -- Suggest using rectangular tank within (23" L × 12 "W × 15" H)/231=17 gallon; Calculated at a rate of one bubble per second, if left open for 24 hours, the gas reflected at a time can be used for about 15 days (if left open for 8 hours per day, it can be used for 45 days at a time)

## Questions & Answers

**Q: Do we have to wait for the raw materials to react for 8 hours?**
A: 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.

**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.

Received product and worked doesn’t leak but the magnetic Solinoid did not work so I can’t say the product worked right, the paining on the valves was also scratched and I did not like that seeing as this is a new product I am going to let the gas finish and return it was not happy with what I received
