Fresh water aquariums are easy to maintain and can be very attractive-They look even better once you put suitable plants in them that also provide a better environment for your fish. When you have to select plants for your aquarium then do look for ones that enable you clean the environment in the aquarium and also make it like natural habitat of fish you are keeping. These plants provide a hiding place to fish so that they can feel secure.
These plants help in keeping balanced water chemistry and in producing oxygen for inhabitants. Before you go for any specific kind of plant, think about the conditions required for it to be there in your freshwater aquarium tank. These conditions include space, water pH, lighting and good substrate. For example there are some plants that you have to put some of the plants in clay. For this you need clay planters. These help you plant them easily. Some of them can also be planted directly into the gravel. Depending on the conditions you have for your aquarium, you can experiment a little and then decide for any particular one.
Plants require different levels of lighting. Look for the lighting conditions and if you want to have some plant with good growth and in a better condition, you do have to keep your freshwater aquarium in a bright place. You also have to keep in view the amount of carbon dioxide exhaled by fish, in there. Plants need this carbon dioxide for photosynthesis. So, keep a balance between the number of fish and the plants. If there doesn't exist a balance then you might have to use carbon dioxide injector for plants.
Before adding aquarium plants do dome research and then go and buy them. You'll save yourselves some money by doing so.
