cristi, intrebarile puse m-au facut sa cred ca este incepator. daca nu este asa, imi cer scuze. ce teste din comert ii poti recomanda pt a afla nivelul doar nivelul NH3? si eu mi-am pus intrebarea asta si nu i-am gasit raspuns.
am cautat pe internet informatii legate de acest subiect si am gasit ceva ce pare destul de bine documentat. o sa postez ce am gasit in engleza, urmand ca dupa ce voi ajunge acasa sa fac si traducerea.
The term "free ammonia" is a misnomer and doesn't mean that it is any easier for the good bacteria to eat. The proper term would really be "un-ionized ammonia" and all it means is that it is ammonia that is floating around looking for another hydrogen atom to bond with. All Amquel+ or Prime does is gives it that extra H converting it from NH3 to NH4+. In fact without using Amquel+ or Prime or anything along those lines in your tank, you will always have a balance of NH3 and NH4+ in your tank. The amount of NH3 is determined by the Ph and the temperature of your tank. In a tank with a total amount of ammonia reading 1.0, with a Ph of 7.0 and at a constant temperature of 78F, 0.0059ppm of that 1.0 reading is NH3 while the rest is NH4+. In that same 1.0 total ammonia reading at a Ph of 8.0 and at a constant temperature of 78F, 0.0558ppm of that 1.0 reading is NH3 with the rest being NH4+. This is why Ph is important because as you can see, at a higher level of Ph you will have more toxic ammonia in your tank at any given time. Someone with a high Ph really needs to use a Amquel+ or Prime type product in order to force all of the ammonia to be NH4+. However, all of this has nothing to do with the speed at which the nitrifying bacteria convert either NH3 or NH4+ to nitrite. Thus your tank was not fully cycled just because you didn't have any free ammonia in your tank, it was simply safer for the fish. Only when your API kit read 0 total ammonia was your tank fully cycled.
