Aquarium DIY CO2 Generator System Kit Carbon Dioxide Reactor Maker with Check Valve for Aquatic Plant Growth Supplies
Feature:
Aquarium CO2 DIY System: Easily create your grow tank CO2 supply system. You only need to prepare 2 carbonated drink bottles and ingredients (citric acid and baking soda).
Cost-effective, simply by self-producing pure CO2 continuously through chemical reactions, saving you money.
Dedicated precision pressure gauge with clear scale for easy observation.
Polished, refined, durable stainless steel finish.
Well-sealed caps and pipes, leak-proof, non-deformed, and non-loosening.
Equipped with a safety valve, the pressure is automatically relieved when the pressure is greater than 4kg, and the pressure of the carbonated beverage bottle is 8kg, which is safe and secure.
The safety valve supports manual pressure relief. When the pressure is lower than 4kg, it can be released manually by pulling the ring of the safety valve, which is very safe.

Specification:
Material: aluminum alloy
Size: about 175mm long
Color: as shown
Working pressure: 0.2-0.4Mpa
Output pressure: 0.4Mpa

Instructions:
1. Add materials. (Ratio of materials: bottle A: citric acid 200g + water 600g; bottle B: baking soda 200g + water 200g)
2. The generator is connected to the bottle body.
3. Initiate the reaction to produce carbon dioxide.

Pressure gauge pressure display operation steps (with video):
1. Set the ratio first, then open the regulating valve, and find that the baking soda is foaming, then close it, and shake the bottle to fully react (do not shake it up and down).
2. When 1KG is not displayed, please use the fine-tuning valve to open the baking soda again to make it foam, close the fine-tuning valve again, and then shake the bottle (do not shake the bottle up and down).
3. If it still doesn't work. Repeat the second action.
4. According to the video operation method, remove the bubble counter, increase the electromagnetic working pressure, and wait for the pressure to reach 1kg (if the pressure gauge does not reach 1KG, please repeat the operation 2-3 times patiently until the pressure rises).
5. Install bubble counters, solenoid valves and other equipment.

Note:
If the pressure gauge is not working, check the pressure. The minimum working pressure is 1kg/cm2.
The bottle shown in this product picture is the effect of shooting, the product is not included, please be aware.
Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you!
Please allow 1-2cm measuring deviation due to manual measurement.
