Hi. I have a 5 gallon freshwater started 4 weeks ago. Had 3 guppies but they died. The most recent a few days ago. I treated for ick a few times and did a 50% water change day after last fish died. Im now doing a fishless cycle, first time. I got a testing kit and the nitrites are super high. There is a lot of info out there so im not sure what to do. Just let the tank ride it out or add something? We'd like to put fish in there soon but want it to be safe. Also dont really want to wait 2 months. Suggestions? Thank you in advance.
