After 3 weeks my tank finally finished it's cycle
after all the nitrite spikes last week and about 4 times of huge water changes this week my hard work finally paid off. Ammonia and Nitrite is at 0 and my fishy survived and look well...... How long should I wait until i start to stock it? I'm thinking waiting another week to buy new fish, but how many fish can you add so that the water parameters won't go unstable and cause a mini cycle?
