Top 10 Charming Medium Light Aquarium Plants

When it comes to aquarium plants, what is the first thing coming to your mind? Generally, diverse aquarium plants vary in light requirements, from low to medium and high light. Here in this article, we are going to take a look at the best medium-light aquarium plants.

What is medium light for plants

Medium light for plants indicates approximately 10 hours of lighting, a light intensity of 20-40 lumens/liter, and PAR values of 30-80 PAR or 50-120 μmol/s. Plus, here are some examples of medium-light aquarium plants. Red flame sword, Micro sword, Pearl weed, Peace lily, and Philodendron are excellent options for aquariums.

In addition to lighting, you should meet other requirements. For instance, appropriate living conditions, temperature, fertilization, and carbon dioxide concentration, while these factors will affect the rate of photosynthesis.

What are the effects of medium light plants in the tank

Effects of medium light plants in your tank

  • Balanced aquatic ecosystem

Medium-light plants can contribute to a balanced and natural aquatic environment. They help absorb excess nutrients, reduce algae growth, and provide shelter and hiding places for fish and other marine organisms.

  • Oxygen production

Through photosynthesis, medium-light plants release oxygen into the water, improving oxygen levels for fish and other organisms in the tank. This is typically beneficial in densely stocked aquariums or tanks with poor water circulation.

  • Carbon dioxide absorption

During photosynthesis, medium light plants absorb carbon dioxide (CO2) from the water, which helps maintain a stable pH level and prevents excessive CO2 buildup. It benefits the overall water chemistry and the health of aquatic inhabitants.

  • Aesthetically pleasing

Medium-light plants often feature vibrant colors, unique leaf shapes, and different growth patterns. They appeal visually to the aquarium, creating a more natural and attractive underwater landscape.

  • Nutrient uptake

Medium-light plants require nutrients to grow, including essential macronutrients (nitrogen, phosphorus, and potassium) and micronutrients (such as iron and magnesium). Their presence in the tank helps maintain a nutrient balance and can reduce the likelihood of nutrient deficiencies or imbalances.
