Fish tank use to fill up gap.Two in one aquarium. Top tank is built with open bottom design to allow fish to move between tank. Cleaning is make simple. Changing of water for top tank is not require. Partial change of water or removing of unwanted particles if needed is carried out in the bottom tank that include feeding.

ROLE OF BACTERIA IN THE NITROGEN CYCLE

Many different kinds of bacteria are present in our bodies and throughout the environment, including water. There are aerobic (good) bacteria, which require oxygen, and anaerobic (bad) bacteria, which do not require oxygen.

The bacteria in the aquarium will establish themselves on all the surfaces that are suitable for them to live on. These include the gravel, ornaments, tank walls and more importantly, the filter, where a majority of them will accumulate.

Aerobic bacteria need three things to survive: a habitat, food and oxygen. The filter contains a medium that provides a large surface area on which bacteria colonies can establish themselves. The water flowing through the filter provides them with good food and oxygen. Food is derived from the decaying organic material in the water column ( uneaten food, fish waste, decaying plant matter). And the movement of flowing water will permit gaseous exchanges to occur, and as a result, oxygen to be produced.

Normally, it takes the good bacteria approximately six to eight to be properly established before they can cope with a new aquarium's bio-load.

The environment in a newly set-up aquarium is a sterile one. At this point, there simply any enough good bacteria to take on the bio-load. Therefore the amount of fish and food added to it should be limited, until adequate bacteria colonies are established.

The first bacteria that develop are the nitrosomonas, which are hardy and efficient. Once established, these bacteria ingest and break down ammonia into nitrite -- this process occurs in the first stage of the nitrogen cycle. Ammonia, a by-product derived from the decomposition of the organic matter, is extremely toxic to fish. Its level will peak then decline, as the growing population of nitrosomonas feed on it.

In the next stage of the cycle, bacteria called nitrobacter will in turn ingest the nitrite and convert it into nitrate, which is the least toxic form of the three by-products. However, unlike nitrosomonas, nitrobacter are slower to develop and less hardy. As they are not as robust and easily affected by chemical treatments and changes in water quality.

In nature, plants and algae absorb nitrate for use in metabolic processes: but in an aquarium, it is almost impossible to have a large enough number of plants to absorb the entire nitrate in it. Therefore, the best way to remove nitrate and keep the environment stable is through regular water change.

  • hey uhm goodluck when you have kids ^.^

  • @alizcool1 yeah, the tank is way to nice =)

  • Nice tank but I don't think it matches your house.

  • Thumbs up for posting the nitrogen cycle info, I doubt most of the viewers read it, Nor understand that it is required .

  • Thats tight as hell though 

  • My dogs would jump in their and try to catch the fish  =( It's a gorgeous tank!
