The presence of ammonia and ammonia assay NH4/NH3
Ammonia (NH3) and ammonium ion (NH4 +), depending on the pH of water are normally present in water, if water heavily contaminated with excessive amounts of food offered to the fish. Food remains at the bottom of the aquarium and begins to decay. Also, the product of fish excrement in the initial phase of ammonia and ammonium. More
specifically, there may be an increase in ammonia and ammonium in the initial stage of the aquarium, where only this is not enough "running" or "cikliran. The sharp increase of these nitrogen compounds occur if the
filter medium is not populated enough nitrifying bacteria Nitrosomonas, which through the presence of oxygen O2 convert ammonium ion or ammonia into Nitrite NO2.
• The presence of nitrite in test NO2
Nitrites occur in the aquarium water as a secondary product of the excess food and fish excrement. Bacteria
Nitrosomonas convert ammonia and ammonium ion to nitrite, which are still highly toxic and their
value does not exceed 0.1 mg / l. However, because after about 30 days to filter
material settles in another type of bacteria called Nitrobacter, only those converted by the oxygen
Nitrite and in a nitrogen compound called Nitrate NO3, which is much less toxic to fish, but
still so much that it should be removed from the water.
• The presence of nitrates, NO3 assay
Nitrates occur in the third or final stage of nitrification and fish less, but still much
toxic, not to exceed the limit of 50 mg / l, for discussion and to 20 mg / l of aquarium water. Since the
normal biological filters nitrate can be removed from the aquarium water is only a partial solution
water changes (at least 1 / 3 per week), but also by planting fast growing plants that pump Nitrate
from water as a nutrient. Such plants are Cabomba, Limnophilla sesilliflora, ceratophylum demersum and the like.
• The acidity or alkalinity of the assay Ph
Ph value of water, we can see or react as an acid or base. With pH is given hydrogen ion concentration of 1-14. Water with a pH of 7 is neutral. Below pH 7 is acidic and above pH 7 is bazična.Še especially in spawning discus, it is important that the water is acidic. The acidic water is very poor developing mold and some bacteria, which can be taken advantage of.
• Total hardness of the test Gh
Total hardness form carbonate and carbonate hardness, which means that the sum of the concentrations of calcium and magnesium bicarbonate and calcium and magnesium salts.
• carbonate hardness of the test Kh
Carbonate hardness is the concentration of calcium and magnesium bicarbonate.
