Aquarium plants are often thought of as an afterthought. Many people set up their tanks with the fish first and then add a few plants here and there. But if you really want your aquarium to thrive, you need to give some thought to the plants. They play an important role in the ecosystem and need the right conditions to flourish. One of those conditions is carbon dioxide (CO2).
Plants need CO2 for photosynthesis, which is how they convert light into energy. In an aquarium, there is often not enough CO2 for the plants to get what they need. This can lead to stunted growth or even death.
Adding CO2 to your aquarium is not difficult and can make a big difference for your plants. There are a few different ways to do it and you can find what works best for you. But if you want your aquarium plants to really thrive, CO2 is a must.
