sera guide - Splendid plants in your aquarium

4 Light energy – the correct light Plants are able to produce complex mole- cules (carbohydrates/sugars) they require for their growth from carbon dioxide (CO2) and water while utilizing light energy. During this process, which is called photo synthesis, plants also produce oxygen that the fish need for breathing. Aquarium plants require light of a certain composition for photo synthesis. The special sera plant color fluorescent tube provides red/blue color light. It perfectly matches the requirements of aquarium plants and en- hances the natural colors of fish and plants. It can be combined with the other sera fluo- rescent tubes without any problems. This gives you the possibility to fulfill the light re- quirements of both fish and plants in the same way.
