A healthy aquarium is a balanced ecosystem where all living organisms exist interdependently and none outgrows its place in the system. Fish and other animals produce waste that will become toxic if allowed to build up. This applies to cold, tropical, and fresh- and saltwater aquariums alike. Plants can play an integral role in the aquarium ecosystem.
While most species that live in aquariums depend on small levels of nitrates, nitrate levels that are too high can kill fish and other inhabitants of your aquarium. Nitrate occur as ammonia breaks down, and therefore may have a variety of sources. One major source is overfeeding, but items such as under gravel filters and filter pads can also contribute to nitrate levels. Your goal in lowering nitrate levels should be to reduce nitrate in the tank without shocking the fish by dramatically changing their environment in a short period of time.
Maintaining safe levels of dissolved chemicals in the aquarium is essential for keeping fish healthy and happy. Generally speaking, this is a case of correct filtering, water changing and feeding. If these factors are maintained regularly then problems with chemical buildup should be kept to a minimum.
Low levels of nitrates in an aquarium are not harmful to fish. However, excessive nitrates, 20 ppm or more, will cause the water to look dirty and stress your fish, leading to disease or death. To be able to lower the nitrate levels in your tank, you must understand the nitrogen cycle and what increases nitrates. In the nitrogen cycle of a fish tank, "good" bacteria break down the ammonia from fish waste and other debris into nitrites. Good bacteria then break down the nitrites into nitrates. High nitrate levels occur when there is too much ammonia in the tank…
Sugar, or dextrose, is used in reef and other saltwater tanks to reduce the nitrate and phosphate levels. The dextrose, as a carbon source, encourages the growth of beneficial bacterial colonies that neutralize nitrates as well as phosphates. Proper oxygenation of the aquarium is necessary for this process to occur safely, and a skimmer must run to capture the resultant organic matter.
High nitrate levels in saltwater aquariums cause algae blooms and adversely affect plants and fish. Nitrate is produced as waste breaks down. Waste cycles from ammonia to nitrite to nitrate. Discover why nitrate levels in your aquarium are too high before lowering it. This helps you prevent nitrate levels from rising again. Common causes are bioballs, biowheels, filter pads, foam blocks and tubes, overfeeding, undergravel filters and lack of water changes. Too many fish can cause nitrate levels to rise; there should be three inches of fish per square foot of surface area.
Nitrate is a nutrient created as a result of dead animals, animal waste and plant decay in an aquarium. The correct nitrate level in a saltwater tank is important because it can affect the health of the animals. A level of 10 to 35 ppm for a tank harboring fish is an ideal level. A tank that contains coral must be between .25 to 5 ppm.
In saltwater aquariums, nitrates get into the water mainly through fish waste and deteriorating algae. If your nitrate levels are on the rise, that generally indicates a decrease in overall water quality. You can lower nitrates and then keep them low in your salt water aquarium in a variety of ways.
The best way to lower the nitrates in a reef tank is through frequent water changes. Lower the nitrates in a reef tank with tips from the owner of a fish pet store in this free video on pet care.
Nitrates in a reef fish tank can slow the growth of the coral reef and may affect the fish if not kept at acceptable levels. Lower the nitrates in a reef tank with tips from the manager of a fish pet store in this free video on pet care.
In order to maintain a healthy saltwater tank, you need to keep an eye on nitrate levels. You should get into the habit of testing your tank water's nitrate levels on a regular basis. Normally, a healthy saltwater tank has five to 10 ppm (parts per million) of nitrate. Any higher, and the nitrates will deplete all of the oxygen in the water, which can potentially kill your fish and plants.
In order to have a thriving reef aquarium, you need the nitrate level to be only less than 5 ppm (parts per million). Some salt water fish keepers say that the level should be .25 ppm. Nitrates are the chemical produced from creature waste, as well as any rotting uneaten food. You need to keep a close eye on your reef tank's nitrate levels.
The environment in a fish tank is a very delicate ecosystem. You have to find the right balance between having enough and having too much nitrite in the tank. Too much nitrite is bad for the fish. Knowing the steps to take to lower the nitire levels means life or death to your fish.
High nitrate levels in a fish tank could make fish sick or kill them. It can also cause a bad odor or cloud water. If you think your nitrate is high or you test the water and confirm it is, then you should lower the levels before fish begin dying off.
