At first the water may look a little cloudy, but this is normal for a new tank. If you feed your fish very sparingly for the first two weeks, this should clear up and remain clear. Plants are important in an aquarium, but not as important as many people would have you to believe. Plants do not provide the fish will all the oxygen that they need. In spit of everything that you may have heard, fish do very well without the plants.
Plants add oxygen to the water and use up carbon dioxide only wen they are actively making food.
Green plants will make their won food by taking in the carbon dioxide and then changing it chemically so that they are able to use it. Underwater plants do add a great deal of beauty to your aquarium. The plants will grow in the water to make a more natural surrounding for your fish. The fish can hide in the leaves of the plants and love to lay their eggs here. Also, a well planted aquarium is less likely to develop green water.
