I have a 5 gallon tank cycling with 3 tiger barbs, bigger home is on the way and have been testing the ammonia and nitrite levels with API kits. The tank has now been running for 4 days @~80F with 2 ~20% water changes on day 2 and 3. Day 3's ammonia levels were between 0 and 0.25 ppm and nitrite levels were 0ppm. I also added Cycle, just to see if it works. Just tested, Day 4, and ammonia levels are a little higher but still between 0 and 0.25. Nitrites are 0.25, maybe even a little higher.

Is it normal to see nitrites this soon? From reading other posts it seems that other people didn't see it until a week or so. Maybe Cycle worked? Also, should I continue the water changes? I know the ideal nitrite level is 0 but what level is the max for ammonia and nitrite I should let it get to while it cycles? Thanks. :-)
