Okay I am having trouble with the cycle on my 10g. I started cycling like the first week of Feb. Added the ammonia, then watched the NI one day checked and they were in the light purple checked a few days later it was blue again. Could it have spiked? I think it did as when I checked again the NA was up 1 color from .5. Checked again today and its back at .5. That is normal for my other cycled 10g. Ammonia is still at like 2.0. Could it have finished cycling? I wish I would have monitored a bit better but some of my liquids are running low and I don't have the money to restock so I have been watching it and trying not to over test. Though I think I under tested. I did do a water change once I noticed a change in the NA, and a few days later it was back or still at .5. Not sure what to do. I am thinking it may be done minus the extreme ammonia, but was hoping someone else may be able to shed some light and tell me their opinion and if once I get the ammonia down it would be safe to add fish.
