My 70L tank has been cycling with 6 neon tetras for 3 days, on the first day, ammonia was at 0.25ppm, second day 0ppm and third day 0ppm. Nitrites are at 0ppm, and nitrates on the second day were 3ppm. I changed the water the day before yesterday. Should I do a 20% water change, or not? Because my ammonia is low so I dont want the benificial bacteria to starve. Or should I only change the water when ammonia levels are more than 1ppm?
