seems like bacteria were dead upon arrival
Case of back luck but it seems bacteria were dead upon arrival - i tried dosing as per bottle instructions and there were no changes in nitrate levels over the course of 3 weeks.

Tried and true
Works. It helps to establish the tank over time. There’s no instant cure and you cannot get fish or axolotl or anything in a tank with out any cycle. Wait for it to cycle. Use this. It works well. It takes four weeks to cycle.

Know your water chemistry

It works
It's Quickstart, it's API. It's not bad at all. It does what's supposed to do. Just add it during big water changes (30%+) and you are golden. Good to buy you some time when treating ammonia too.
