So, I've had my tank setup for about 3 weeks, and have a good deal of Ludwigia plant stock (going low tech, simple fresh) as well as some Anubias, an Amazon sword, two Java ferns, Anacharis, and a few other random plants from an assorted batch. Now, I've been keeping up with checking my water levels every 1-2 days and yesterday I noticed my Ammonia went from 4ppm down to 0.5ppm. I put in about 3-4 pinches of fish flakes and left it for 24 hours. Ammonia levels remain at about 0.25-0.5ppm and my nitrites are at about 5ppm. My Nitrates went from about 10ppm up to 80ppm in two days. I'm not sure where in my cycle I am as my nitrites haven't dipped in almost a week but my nitrates have just appeared. What should I do to continue forward and where do you think I'd be at in regards to stocking with fish? Pics attached of current setup.
