Good afternoon, I have a concern about the 5-gallon tank I am attempting to cycle. The tank is meant for my two African dwarf frogs currently residing in the smaller quarantine tank. The 5-gallon has gravel, a log, a small Amazon sword, it is stocked with a heater that keeps the temperature at about 83-85 degrees F and a Tom submersible mini-filter. For the first three days, I have added Nutrafin Cycle in the amounts described on the box. No other seeding materials were available to me. I have had it set up thus for almost a month (it will be exactly a month in three days). I got the Ammonia up to 4-5 ppm and it is staying there. The PH is at 7.2, and I have not seen any nitrites. My question is: how long is this supposed to take? I am on the verge of losing all patience and beginning to worry that I am doing something wrong and the nitrites will never show.
