There are two basic requirements for plants to grow through photosynthesis; nutrients and light.  The most important nutrient for plant growth is carbon.

By introducing CO2 into the aquarium, plants can achieve healthy growth faster and therefore out compete algae.

Since carbon dioxide (CO2) is abundant in the atmosphere, plants simply draw their carbon directly from CO2 in order to photosynthesize and grow.  In an aquarium, CO2 levels are naturally very low and without any supplementation, submerged aquatic plants will not be able to grow properly.  When CO2 is a limiting factor, plants cannot fully utilize all the available light to photosynthesize.  This can allow algae to grow and compete with the plants for nutrients, further stunting plant growth.  By introducing CO2 into the aquarium, plants can achieve healthy growth faster and therefore out compete algae.


At a fraction of the cost for using pressurized gas, you can provide CO2 to your aquarium for up to two months.

The introduction of carbon into an aquarium is typically achieved by using a pressurized gas tank controlled by a regulator, solenoid and needle valve.  Although pressurized CO2 is the best way to go for larger aquariums 20 gallons or above, these units can cost an average of $300 for a complete set up.  This type of CO2 injection can be dangerous for beginners, not only for the fact that you’re dealing with pressurized gas but also because turning the gas too high and releasing too much CO2 can kill your livestock very quickly.

The simple instructions and ease of use allow any beginner or experienced hobbyist to achieve the best plant growth by introducing CO2 to their aquarium.  The Nature Bottle utilizes a natural and proven concept to provide the right amount of CO2 suitable for planted aquariums.  We recommend using one bottle for every 20 gallons of water, so if your tank is larger, multiple bottles can be employed concurrently.


Step 1: Water
Add 300 ml of warm water between 100° to 120°F to your Nature Bottle.  Do not add water that’s too hot, it may damage the bottle and affect performance.

Step 2: Shake
Tighten the cap and shake the Nature Bottle for one minute until all solids have dissolved and you’re left with liquid only.

Step 3: Wait
Allow the Nature Bottle to sit for 24 hours without interruption or disturbance.  The liquid will thicken into a gel like consistency.  After 24 hours, invert the bottle to ensure that the liquid is fully solidified.  If not, wait another hour and check again.

Step 4: Activate
Remove the cap and clean off any gel that remains on the bottleneck.  Using the cap as a measuring device, add 2/3 to 1 capful of Bio-Powder into the Nature Bottle followed by 150ml of lukewarm, room temperature water around 77°.   Install the reaction cap onto the bottle, no shaking is required.  Connect the flexible tubing on one end to the reaction cap and the other through the suction cup and onto the diffuser.  Place the diffuser into your aquarium and wait.

Step 5: React
During initial use, CO2 gas output will fluctuate but overtime, the reaction speed will stabilize and slow down.  The Nature Bottle will continue to work for up to 60 days depending on room temperature.  Increased temperatures will speed up the reaction process and shorten the usage time.

Step 6: Repeat
When CO2 output slows down or stops completely, remove the cap and pour the liquid out of the Nature Bottle.  Repeat steps 4 to 6 until the gel is fully consumed.


The Nature Bottle is designed for aquariums 10 to 30 gallons.  For smaller tanks, you run the risk of providing too much Co2 and depleting oxygen levels which can be deadly for your fish and shrimp. If you choose to use the Nature Bottle on nano tanks smaller than 10 gallons, we recommend running an air pump lights are off or if you notice your fish gasping at the surface.   If you don’t have an air pump, creating any surface agitation in the water will also provide oxygen to degas excessive CO2.

Usage life of the Nature Bottle can vary depending on the temperature.  Recommended room temperature ranges from 68° to 86°.  The higher the temperature, the faster the CO2 depletes itself and the shorter the duration of usage.  As a general rule of thumb, the Nature bottle will last 30 to 50 days during winter and 40 to 60 days during summer.

Gas output is non adjustable, we do not recommend the use of needle valves, solenoids, or any other devices which can cause damage to the Nature Bottle.

Do not tilt or shake the bottle during operation in order to prevent reaction liquid from getting into the aquarium.  Minor amounts of alcohol may be produced from the solution, which is normal and harmless.  In the event that any reaction liquid leaks into the aquarium, an oxygen deficiency can occur but a simple 30-50% water change will correct the issue.  Running an air pump to degas some CO2 will also help.

Clean and remove any gel that forms on the bottleneck before initial use to prevent build up or jamming at the gas outlet.  If any reaction liquid is found inside the flexible tubing, simply clean it with water.
