Fish tank water usually turns green due to an excess of algae in the tank. A sudden algae bloom can be caused by overfeeding the fish, overstocking or direct sunlight, among other causes.Know More
Most fish do not need to eat multiple times a day or even every day. Find out the feeding requirements of the fish in the tank. If there are food particles floating in the tank even 10 minutes after a feeding session, there could be overfeeding. The excess food provides nutrition to the algae in the water, causing it to multiply and turn the water a greenish color. Cut back on the food till all the food that is given is consumed soon after the feeding session.
Another cause for excess algae in the tank is dirty water. Algae grow rapidly when the nitrate levels in the water increase. To prevent this and to keep the tank clean, change 25 to 30 percent of the water on a frequent basis. Algae growth also accelerates with too much light. Move the aquarium away from direct sunlight, or keep the blinds or curtains drawn. If the aquarium has its own artificial light, limit the amount of time that it is kept switched on.
Too many fish in a tank can also cause the water to turn green. Overpopulation causes an increased bio-load on the water, with the existing bacteria trying to keep up with the large amounts of ammonia produced by the fish.Learn more about Aquatic Pets
Brown algae commonly appears in newly established saltwater aquariums. It is not true algae, but rather an accumulation of single-celled organisms known as diatoms. Diatoms appear in response to silicate, which occurs in new water added to an aquarium before filtration is established to remove it.Full Answer >
To clean a fresh-water fish tank once per week, 10 to 15 percent of the existing water should be removed, and the gravel and decorations should be cleaned using a siphon. Additionally, an algae scraper should be used to remove algae. Refill the tank with clean, chlorine-free water as close to the original water temperature as possible. It is not necessary to remove the fish from the tank.Full Answer >
Determining the volume of a fish tank requires fairly simple math calculations that can be determined by taking the tank's measurements. For tanks that come in basic shapes, such as spheres or rectangles, the process is easier than irregular shapes.Full Answer >
Build your own fish tank by attaching four pieces of glass to a glass bottom using caulk and adding a light on the top. This project takes less than 60 minutes, though it may take longer it you are cutting your own glass. You need five pieces of glass, duct tape, clear aquarium silicone caulk, a Coralife mini-compact light fixture, a caulking gun, acetone, a razor blade and some paper towels.Full Answer >
