If your tank is located in direct sunlight and you are having an algae problem, it is best to relocate the tank. By following a maintenance schedule, you will be sure to keep a clean, clear and healthy tank. Aquarium care is essential and must be performed regularly to ensure the long and happy life of your fish. You will also need to buy a scraper or a scratch pad to clean the glass. A regular cleaning tool will not be strong enough to remove the algae from the glass. It is very important to aim the filter head down into the water. Failure to do so will result in a build up of salt on the lid of the tank. Good lighting and a strong and efficient filter are a necessity. Colored rock or dead crushed coral make a nice addition to the aquarium, and may help to make the fish feel more at home. A few varieties of guppies are the Fantail, Flagtail, Spadetail, Deltatail and the Roundtail. The names of all of these different types of guppies focus on the tails because they are so remarkable and unique. Take caution when deciding to use florescent lights if your tank has a depth of 20" or more. The low growing plants, or plants with multiple leave levels will suffer from a lack of light as the florescent rays will not provide enough light. Once you have figured out what type of lighting you will use, you must turn your attention to the hardness of the water. A few examples of tropical invertebrates are tubeworms, red hermit crabs, cleaner shrimp and the sea apple. All of this marine life is compatible in terms of water conditions. They require a water temperature between seventy five and seventy nine degrees Fahrenheit, a P.H. between 8.2 and 8.4 and a salinity content of 1.020-1.024.
