Thanks and Welcome.

Thanks.

welcome

Plants utilize CO2 during photosynthesis to produce oxygen (O2) and organic compounds. Aquatic plants can indeed uptake CO2 from water of RAS incorporating plants into a separate tank within the recirculation circuit. It can be beneficial as they can help reduce CO2 levels in the water. However, it's essential to ensure proper management and monitoring to optimize the effectiveness of this approach. Aquatic plants primarily uptake nitrogen in the form of nitrates (NO3-) and ammonium (NH4+) rather than directly absorbing dissolved nitrogen gas (N2). Nitrogen gas is relatively inert and not readily available for uptake by most plants, including aquatic ones. In the nitrogen cycle, nitrogen gas (N2) from the atmosphere is converted into nitrates ((NO3-) through a process called nitrogen fixation. Nitrogen fixation can occur through both biological and non-biological processes. Therefore, while aquatic plants do play a crucial role in nitrogen cycling by absorbing these nitrogen compounds BUT they do not directly uptake dissolved nitrogen gas.
