How To Make a CO2 Reactor for an Aquarium

Plants need CO2 for healthy growth.If you have plants in your aquarium, injecting the water with CO2 will help them.You can make your own CO2 reactor system with bottles, tubing, and aquarium equipment.An expensive CO2 system can be purchased from a pet store.

Step 1: Take 200 g of baking soda and put it in a bottle.

If you empty out a bottle of juice or soda, rinse it out with cold water.Put a funnel in the mouth of the bottle and pour baking soda into it.You can keep track of which bottle it is by writing an A on it with a marker.Baking soda can be purchased at a grocery store or online.

Step 2: The water should be added to the baking soda bottle.

The funnel can be used to pour the water into the bottle.The water will be cloudy and white when you put it in.Baking soda and water can be used in this bottle if you need to generate more CO2.It’s important to keep the mixture to a 3:1 ratio.

Step 3: 200 g of citric acid can be added to a second bottle.

You can buy it online or in grocery stores.Remove the inside of the funnel and place it over the bottle.Slowly pour the acid into the funnel.A B is written on the bottle with a marker.The acid will be in a powder form.A component of certain candy is bicyle acid, an ingredient that is commonly used in pickling.

Step 4: The water should be poured into the bottle.

Measure out the water with a measuring cup and pour it into a bottle.The solution can be seen at the bottom of the bottle.If you are trying to generate more CO2 by increasing the amount of baking soda you use, make sure to use more citric acid than you did before.The ratio of citric acid to water should be 1:3.

Step 5: To mix the solutions, shake both bottles.

Shake the bottles vigorously to mix the solutions and start the CO2 reaction.You should be able to see the bubbles in the bottles.Remove the caps when they are mixed.

Step 6: A CO2 generator kit can be purchased at an aquarium or online.

A CO2 generator kit has plastic tubing connecting 2 caps and should include a pressure gauge and valve.Sometimes a piece of plastic is used to connect the tubing.The pressure gauge and valve will allow you to regulate the amount of CO2 in your tank.Depending on the kit, it can cost anywhere from $10-$25.You can read the instructions that come with your kit.If you don’t have a CO2 generator kit, you will not be able to regulate theCO2 going into your tank, which could be dangerous for pets and vegetation.

Step 7: Attach the pressure gauge cap to the bottle.

Take the tubing out of the cap and put it into the bottle.Then, turn the cap clockwise.

Step 8: The baking soda bottle has a valve on it.

Before hooking up the bottles, turn the valve clockwise.Place the tube coming out of the cap into the baking soda bottle.To tighten the cap, turn it clockwise.The baking soda bottle will produce a chemical reaction that will generate CO2 if the bottles are connected.

Step 9: The bubble counter needs to be connected to the end of the tubing.

A bubble counter is a piece of plastic that diffuses CO2 into your tank.The counter should be filled with water.Take the plastic tubing from your valve and put it in the bubble counter.If you have a bubble counter, you can monitor how much CO2 is being generated by your system.

Step 10: The bubble counter needs to be connected to more tubing.

You should get tubing that is long enough to reach the bottom of your tank.Attach the tubing to the output valve on the bubble counter.

Step 11: The end of the tubing needs to be connected.

You can buy a diffuser at a pet store.The end of the tubing needs to be connected.The CO2 setup is complete.CO2 can be diffused into the water by breaking up larger bubbles.

Step 12: The tank should be placed at the bottom of it.

The bubble counter should be filled with bubbles every few seconds.This is a sign that the system is working correctly.You should see bubbles coming out of your diffuser as the CO2 moves through the tubes.It may take 1-2 minutes for the CO2 bubbles to reach you.

Step 13: The valve should be adjusted to increase or decrease the CO2 in the tank.

To reduce the amount of CO2 being generated, turn the valve clockwise.To increase the amount of CO2, turn the valve clockwise.A rule of thumb for most tank setup is 10 bubbles per minute per 100 l of water.The amount of CO2 in your tank depends on a number of factors.If you want to know the level of CO2 in your water, you can use a drop checker or a glass device.

Step 14: Use an air pump if you want to turn off your system at night.

If you leave your system on at night, it may cause CO2 poisoning for your fish.The valve should be turned clockwise at night.If you want to counteract the excess CO2 in the tank, you can purchase an air pump and place it on a timer.

Step 15: Every 20 days, change the CO2 mix.

When the pressure on the gauge reads 0, open the needle valve.Before mixing a new CO2 mixture, remove the caps from both bottles.Put the bottles back in the water.Replacing the mixture will make sure your tank is getting the correct amount of CO2.
