Hi.
I have been doing a fish in cycle of my 54litre tank which has 3 corrys and a beta in. Ammonia and nitrite levels rose steadily and then dropped sharply very suddenly one day. Down from approx 2ppm ammonia to around 0.3ppm. Nitrite similarly down from almost 400ppb to around 40ppb. However, the readings have remained stable around that for around a week and dont look like going to zero. Below are a few readings from said tank which are just a sample. The tank has been running for approx 2 months.

The tank has been running since december but i was previously doing 50% water changes almost daily in order to control ammonia to approx 0.2/0.3ppm but i was getting nowhere in terms of a cycle. No nitrites and no nitrates. So i decided to stop the water changes and just dose with prime daily. This appeared to work, ammonia and nitrites rose and then dropped drastically one day, but they havnt reached zero.
Any advice welcome. Cheers.
