I started my 75g with 6 damsels (lost one right off due to fin injury), ammonia spiked after about a week, moved them out to QT tank. Since then (3 weeks later), the ammonia part of the cycle has completed and nitrites are climbing rapidly.
Ammonia officially hit zero yesterday, after 4 weeks since the start.
I don't have anything in the tank now to produce much ammonia - 4 small LR pieces, and live sand, and a whole bunch of diatoms or something covering everything.
Should I consider an external source of ammonia, to keep the first stage bacteria alive and well, or is what I've got in there sufficient?
