10 gallon fishless cycle started on Dec 2st. I added some gravel from an established tank. Added 3 Amazon swords, 1 anubias nano, 1 marino moss ball, 1 square of java fern, and 1 floating moss ball on Jan 1. Have been using the fish food method for ammonia because I can't find suitable ammonia locally. Ammonia has been steady at 1 ppm, nitrites are 5 ppm, nitrates 20 ppm. On Wednesday, the ammonia levels dropped to 0, nitrites and nitrates the same. I expected the nitrites to start to lower but they haven't. Today, ammonia 0, nitrites 5, and nitrates 10. I have been adding fish food every 12 hours. Temp is 77.7. pH is 7.6. Should I start adding aquarium-grade ammonia? I suspect something else is eating the ammonia and I need to add more to complete the cycling process.
