I used Fluval's "Cycle" biological booster to cycle my aquarium per directions on the bottle. I don't quite understand how this is supposed to work. Was I supposed to actually "ADD FISH IMMEDIATELY" like the bottle said for it to work properly? Was I supposed to feed my aquarium ammonia during the 3 day dosing period? Here are my readings: using api freshwater master kit Water source: rain water ph 7.2 ammonia 0.25 ppm nitrites 0 ppm nitrites 0 ppm Day 1: ph 6.6 ammonia 0.50 ppm nitrites 0 ppm nitrates 5.0 ppm Day 2: ph 6.6 ammonia 1.0 ppm nitrites 0 ppm nitrates 10-20 ppm Day 3: ph 6.6 ammonia 1.0 ppm nitrites 0 ppm nitrates 10-20 ppm I'm not really sure what my aquarium is doing. I'm getting nitrates but I'm not getting nitrites?... and the ammonia isn't going down. So where are all these nitrates coming from? Should I do a water change then add fish?
