Once you have knowledge of set up your tropical aquarium the next step is to 'cycle' it. This process produces beneficial bacteria that shall process the waste ammonia from your fish and convert it into nitrites and then into relatively harmless nitrates. Subsequent to adding fish to an uncycled tank the toxic ammonia and nitrite grades shall rise to a dangerous high until there exists sufficient numbers of bacteria to convert them into fewer toxic nitrates. Sequential to overcome this methods have been devised to encourage the growth regarding the bacteria. The traditional method is to sum a little 'hardy' fish that shall make ammonia to encourage bacteria growth while the tank is 'cycling'. This method is very stressful for the fish, many of which die or are damaged by the process. The toxic ammonia burns the gills and leads to permanent damage. At the end regarding the 'cycling' you can be left with fish in poor condition which you can not need in your aquarium.A better, more humane method to cycle the tank is to use a fishless cycling method. It uses household ammonia like a source, rather than live fish, and a bacteria religion obtained from a well tank or purchased from an aquarium supplier.The Bacteria Starter CultureYou can obtain a starter bacteria religion by adding some gravel, filter moderate or rock from a healthy, aged tropical fish tank. Whether you do not hold a source there exists commercial products available, for example StressZyme or Hagen's Cycle. The religion shall release a quick beginning to producing a colony of bacteria but you should possibly use this method without a starter culture. It shall take a bit detailed then to cycle your tank.
The AmmoniaPurchase some unscented, additive free 100% ammonia. Some aquarium supply shops are now selling ammonia for this purpose. Whether you have knowledge of a chemist or science teacher they should be can obtain you some pure ammonia from a science department supplier..The Tank TemperatureThe bacteria (Nitrosomonas and Nitrobacter) thrive greatest at higher heat than is usually used for a tropical tank so during the cycling increase the heat to between 30 and 35 C (85-95F). When you sum the fish you can turn it below again.Testing KitA testing kit to confirm the ammonia and nitrite grades is essential to test the grades and to indicate when cycling is complete.The Fishless Cycling MethodExtra aeration is recommended while cycling as bacteria need oxygen to grow. Increase the aeration through the tank and filter if possible. You should sum an extra space stone or even use an extra push if one is available. Sum your bacteria culture, then sum about a spoon of ammonia for a mini tank. Increase this for a larger tank. Let about an hour for the ammonia to circulate then test. The ammonia position should be between six mg/L (or 5ppm). Sum some more ammonia if the position is too low. Leave the tank alone for a little days then test again.At this stage the ammonia position should begin to drop and the nitrite position to rise. This means that the bacteria are doing their job of processing the ammonia. Sum some more ammonia when it drops to zero to release the bacteria more to work on. The nitrite position should rise until it reaches a maximum then begin to drop as the nitrites are converted into relatively harmless nitrates. 3 or 4 days subsequent to the maximum nitrite grades are seen the nitrite position should drop to zero. The cycling is now complete.Change about 50-70% regarding the water, carefully so as not to disturb the filter or the gravel bed where the bacteria are colonised. Reset the heat to 25°C, or the recommended heat for your intended fish and let the heat to stabilise for a little hours. Retest for ammonia and nitrites and if the grades are zero you can now begin to sum some fish.It is likely subsequent to cycling the tank to sum all the fish in one leave but this shall result in a spike within the ammonia and nitrite grades that is stressful for the fish and should cause them to grow to diseased. adding the fish slowly shall let the bacteria to grow to cope with the added grades of ammonia excreted by the fish. Even for a fully cycled tank it is advisable to gradually sum the fish. aim to take about a month to fully stock the tank.A fishless cycling method is more efficient and produces a fully cycled tank in a many shorter time than the traditional method of creating use of hardy fish. It shall also be more humane and you can not be left with unwanted, often damaged fish, at the end.
