Days 7 & 8 – Measure ammonia and nitrite. On the first measurement day (Day 2, 4, 5, 7 or 8) that BOTH ammonia and nitrite are both below 0.5 ppm (NH3-N or NO2-N) your tank is close to being cycled. Now start to measure ammonia and nitrite every day. When BOTH ammonia and nitrite are below 0.2 ppm (NH3-N or NO2-N), add another 2 ppm ammonia.

Nitrites are an intermediate product in the nitrogen cycle and are produced by ammonia oxidation with water, or even originate in industrial waste directly.

I have been assuming, since I do have a low level of nitrates that the cycle is progressing, but since I have had the ability to test the water the nitrites have been at 0. The ammonia was holding and not going anywhere, then all of a sudden the cycle took off and the nitrites peaked at 5 ppm.

Once nutrient cycles are balanced, weekly testing is usually would be 5 ppm total ammonia × 28.4% = 1.42 ppm of un-ionized Circular 680 • Page 8. Figure 1. Average ammonia levels in the QUICK START and Control aquariums over time. LOUVAIN GTCL were added for a total of eight fish. Water chemistry: dechlorinated tap water with PH 7.5-7.8, GH/KH 5 degrees, oxygen 7.2 - 7.8 p This is known as the Nitrogen Cycle. At the water temperatures we raise trout it can take six to eight weeks for a tank to fully cycle. Ammonia concentration in In established systems the ammonia level normally reads 0 ppm.

15 chlorine water >0.5 ppm destillerat vatten ammoniak (10 %) ammonia (10%) prevents seal extrusion during the cycle inversion.

Because the beneficial bacteria will not grow in your aquarium to breakdown the ammonia into nitrites. On the other hand, if your tank contains a lot of ammonia more than 8 PPM then it is poisonous for the beneficial bacteria. So high ammonia level is bad! We are beginners so we do not know much about taking care of fish tanks.
