Why Are Some Aquarium Plants Red?
Most aquarium plants are green, but some can be red or other colors. The green color in plants is due to a pigment called chlorophyll. The color we perceive in plants is the light reflected from them. Red plants appear red because of pigments called anthocyanins, which absorb green light and reflect blue, red, and purple light.
Anthocyanins protect plants from stress, such as temperature variations, and act as a sunscreen, shielding them from UV damage. This simple explanation helps us understand how red pigments work in aquarium plants.
 How to Achieve Deeper Red Colors in Aquarium Plants?
Your success in achieving deeper red colors in your aquarium plants will rely on four main factors: quality substrate, CO2, lighting, and fertilization, along with proper maintenance.
Substrate
Invest in a high-quality substrate that provides ample nutrients. We recommend using Fluval Stratum, Muyu Amazon, or Anubias soil for optimal results.
 CO2
Pressurized CO2 is crucial for achieving better results. CO2 aids in gas exchange in plants and helps repair damaged tissues. Intense red and green colors are more pronounced with a CO2 system in your planted aquarium.
Lighting
Lighting plays a crucial role in photosynthesis. Adjust the intensity of the light to enhance plant colors. We recommend using Twinstar E Line Series, S Line Series, or Nemo Extreme Series LEDs specially designed for planted aquariums.
 Fertilization
Plants absorb nutrients from both water and roots. To achieve better plant colors, provide a balanced supply of micro, macro, and iron supplements in proper dosages. We suggest using Masterline Lean or Masterline All-in-One Gold.
Maintenance
Finally, regular maintenance is essential. If you follow all these points, you will surely enjoy a healthy and colorful planted aquarium.
Happy fishkeeping!
