Fluval CO2 Kits
Carbon Dioxide is essential to plant growth. It’s natural state is a gas, but it can be readily dissolved in water. Adding a Fluval CO2 Kit to your take can help to ensure that there is sufficient carbon dioxide in the tank for your plants to grow optimally. This can help to ensure that algae does not start to take over your tank.
Although increasing carbon dioxide levels can be beneficial for your tank, it is also important to ensure that there are not excessive CO2 levels in your tank. Excess CO2 can lead to increased acidity in your tank. It is therefore important to monitor the levels.
Below we take a look at the Fluval CO2 Kits and methods of monitoring the levels.
