How to grow Aquatic plants without any need for Co2 Injection

 Aquatic plants can be grown without the need for CO2 injection in a few ways. Here are some tips for promoting their growth:

1. Lighting: Ensure that your aquatic plants receive sufficient light. Light is a crucial factor for photosynthesis, which is the process by which plants convert light energy into chemical energy to fuel their growth. Consider using full-spectrum aquarium lights or LED lights designed specifically for plant growth. The intensity and duration of light should be appropriate for the type of plants you have.

2. Nutrient-rich substrate: Use a nutrient-rich substrate or soil specifically formulated for aquatic plants. This substrate provides essential nutrients to the plants' root systems, supporting their growth. Look for substrates that contain nutrients like iron, potassium, and micronutrients that are beneficial for plant health.

3. Liquid fertilizers: Supplement the nutrient supply in the water column with liquid fertilizers designed for aquatic plants. These fertilizers typically contain essential nutrients that may be lacking in the water, such as nitrogen, phosphorus, and potassium. Follow the recommended dosage instructions to avoid over-fertilization, which can be harmful to the plants and water quality.

4. CO2 from natural sources: Although you mentioned growing plants without CO2 injection, it's worth noting that aquatic plants can still benefit from naturally occurring carbon dioxide in the water. Carbon dioxide can be generated by the respiration of fish, decomposition of organic matter, and the exchange of gases with the atmosphere. Maintaining good water circulation and surface agitation can help ensure a sufficient supply of CO2 to the plants.

5. Pruning and maintenance: Regularly trim and prune your aquatic plants to promote healthy growth. Removing old or dying leaves and stems stimulates new growth and prevents the buildup of decaying organic matter, which can negatively affect water quality.

6. Water quality: Ensure that the water parameters are suitable for the plants you are growing. Most aquatic plants prefer slightly acidic to neutral pH levels and water hardness within a specific range. Regular water testing and appropriate adjustments can help create an optimal environment for plant growth.

By implementing these tips, you can promote the growth of aquatic plants without the need for additional CO2 injection. However, it's important to note that adding supplemental CO2 can significantly enhance plant growth and is commonly used in high-tech planted aquarium setups for achieving more rapid and robust growth.
