Fish less cycle complete?
I have cycled a 64litre tank using ammonia, having read several articles I was expecting a spike in nitrites this never happened! I kept levels of ammonia at 4ppm but nitrites don't seem to have risen above .25 ppm when I have tested. The tank has been cycling for 2 weeks and I have also added filter start on a couple of occasions. Yesterday I added ammonia to 4ppm and within 24 hrs its at 0 ppm. Nitrates are at around 10 ppm.
My concern is whether there is likely to be a spike in nitrites at some point if I add my fish, 5 harlequins, 2 ottos and a few cherry shrimp.
