Aquarium Pump
A pump is something that isnt essential in an aquarium set up but it is desirable as this causes more oxygen for the fish. The pump is usually attached to a long tube which is in turn connected to a long stone that has small holes through out it; the pump blows air into the holes creating bubbles in the aquarium. This creates a larger surface area therefore creating more oxygen for the fish.
It is also good for decorative purposes. Bubbles can look attractive in a tank and also you get special statues that require pumps, such as opening treasure chests and so on that are used for novelty tanks. Pumps are generally expensive but very easy to get. When purchasing a pump you have to buy the special plastic tubing and the ornament that you want to buy with it, whether it is the long stone or the novelty statue that you want.
Aquarium pumps are easy to buy but are quite expensive however the equipment that goes with the pump is cheap. It is up to you whether you have a pump in your aquarium ,because like I said, it is not essential and only there for decorative purposes and only a small amount of extra oxygen. Most simple fish set ups have pumps but harder fish such as cichlids are fussier about what goes in their tanks and they do not like a lot of bubbles, I speak from experience! Dont worry if bigger cichlids re-arrange your tank, it happens!
When purchasing a pump make sure that you have everything that you need to go with it, the hose and the statue, not to mention a free plug socket. Aquariums use a lot of electricity and you may think that it does not matter but this will of course add to the bill. The statue or the long rock that comes with the pump needs to be maintained to prevent any blockages; you dont want your bubbles to be stuck... now do you! Just give it a clean ever few weeks (in a separate bowl of your tank water) and this will help to prevent blockages. Other than that, that is all you really need to know about pumps. All I can say now is have fun with your new aquarium. It May Not Be as Fast as a Tsunami, But It's Still Coming (adrants)
To demonstrate how global warming will one day turn familiar surroundings into aquarium props, Offsetters suspended lifeboats off the side of buildings and lined Vancouver's streets with water safety gear: life vests under park benches, and a life guard, on duty, in the middle of a promenade.
