Freshwater Plants: Improve the water quality of your freshwater tank while enhancing the natural beauty of your aquarium and providing shelter and security for your fish. In an aquarium, plants clean the water by absorbing the waste materials that are introduced when the fish emanate waste or when fish food is added to the water.
Many plants contain bacterial substances with which they can make even bacteria-contaminated water habitable for fish. Healthy plants, by giving off small amounts of oxygen in the area surrounding their roots, they keep the bottom material from decaying. Bacteria and smaller algae settle on plants, and they too can clean water. Because the plants are intended not only to have a decorative effect, but also to be a vital component of the underwater realm of the aquarium. All plant species should have aproximately the same requirements in regard to water composition, temperature, and light intensity. Where care is concerned, the needs of the plants should be compatible with the needs of the fish. |

Plants not only assimilate, and thereby generate oxygen, they also respire. Just as animals do, plants take in oxygen and give off carbon dioxide. Photosynthesis occurs only in the daytime or when adequate light is available. Respiration, however, is a continuous process, occurring day and night. |
