cycling, nitrite spike
So I got a 20 gallon long, filled it with 10 fish two days later. Unfortunately petco didn't tell me anything about the nitrogen cycle, so I lost 4 fish.
As of now, I have had the tank for 4 weeks, and just yesterday and today have noticed that ammonia has dropped and is reading somewhere between 0 and 0.25ppm. Nitrite has spiked and is off the charts, chart goes up to only 5 ppm and it is at least that dark.
Nitrate on the other hand is starting to show somewhat, somewhere between 5 to 10 ppm.
Should I continue to do water changes daily at 25% of the tank and keep using prime? And, should I continue to feed very sparingly?
