Dymax Carbon D Plus provides the necessary CO2 for thriving aquatic plants. In combination with nutrients and sunlight, this product aids in photosynthesis, allowing plants to produce food. This efficient solution is particularly beneficial for planted aquariums with low CO2 levels, as it is derived from carbon dioxide and promotes the conversion of ferric iron to its liquid form. With Dymax Carbon D Plus, plants can maintain their vibrant colors thanks to quick dissolution and easy absorption into the water. Other benefits include an organic carbon source and availability in 300ml and 500ml sizes.
