| - One of the most important aspects of successful fish keeping is good aquarium maintenance, including routine water changes. Importance If your aquarium looks beautiful and the water is crystal clear, everything is wonderful… right? Unfortunately not. In an established aquarium, bacteria convert ammonia (produced mainly by decaying food and fish waste) to nitrite, and nitrite to nitrate (NO3). Nitrate is the end result of the Nitrogen Cycle, and while it is the least toxic form of nitrogen it does build up over time – to potentially dangerous levels if left unchecked. Changing a portion of the aquarium water on a regular basis is the easiest way to reduce it.
* The buildup of nitrates (nitric acid) can reduce the alkalinity of your water, potentially resulting in a pH drop.
* Phosphates, pheromones and other chemicals can build up between water changes.
* Minerals and trace elements are depleted over time, which can result in a GH drop.
* Poor water quality can lead to infection on a wounded fish.
* Poor water quality puts stress on fish, which is often the root cause of fungus and parasite problems. It has been said that dirty water holds less oxygen, although I do not have any scientific data to back this statement up. Without question, water changes supply clean oxygenated water to your fish – and that’s a good thing!
