There are two answers to this question, is the first thing you need when setting up an aquarium and is the second, what if the tank is so constructed.

Whether an existing or new tank, you are trying to do is to keep the water at a level that is best for your fish, if the first thing that the species is to understand the conditions that would prefer your selected fish. All fish live happier between certain parameters of the water and varies with each type of fish.

Should be in a new container, you can determine if the effect of the nitrogen cycle is, in other words, if the tank is safe and gone with the addition of fish .. The biological filter is not yet clear whether all the fish waste and undigested food would only spike ammonia. This is the first step in the nitrogen cycle and can be easily detected by a test for ammonia.

View As bacteria begin to breed, you are, the ammonia spike converted replaced by a peak of nitrite when ammonia is used by the first set of good bacteria, Nitrosomonas nitrite. This is the second stage of the nitrogen cycle and can be tested with a test nitrite

Since the tank’s cycle is finished, you can see the peaks of nitrite to nitrogen is replaced by a maximum start nitro Spira bacteria to breed and feed on the nitrites into nitrates convert them less harmful. It is the third and final stage of the nitrogen cycle, which show a nitrate test.

Ammonia and nitrite are harmful to fish if it is only when the nitrite levels have fallen back to their original height, it is safe, with the addition of fish

Make sure you slow the fish, a little at a time, so that the nitrogen cycle to catch up to each time. Test the water every two days when adding fish and a partial change of water (up to 30%) when a peak of ammonia and nitrite.

The cycling process can take several weeks and we can not say at what stage you are not testing the waters. It is important to test the water quality of your freshwater tank through the nitrogen cycle.

Thus, the three test kits that you really need only provide follow to the cycle of nitrogen are ammonia, nitrites and nitrates. Fourth, you will need pH test is the acidity of the tank.

If you are the introduction of the fish you must ensure that there is no great difference between the pH in the tank and the pH in the tank, which they came. If yes, then you need to acclimate the fish carefully to avoid shock and stress.

Once your tank is mature, slow tests. You need to regularly test the water and still take note of the results that you might be aware of changes before it the chance to problems. Make it part of your trading routine to the water before you change your water tested regularly, and even more so if your fish is different.

One of the biggest problems in a mature tank is nitrate. Yes, it is far less dangerous than ammonia and nitrite, but the problems with nitrates that it often begins to rise over time. Water your plants regularly and changes will be fighting a long way with nitrate, but it is still worth monitoring on a monthly basis.
