Hello

Hi everyone, new to all this fish keeping just looking a bit of advice, I have a 64l tank set up with gravel and decorations been up and running for about three weeks until I got string algae and I started over again last week, I have zebra danios in the tank and they where there when the algae took hold, I was doing regular water changes to keep the ammonia to a safe level, I had no nitrites before the restart and have had none since, basically all I'm asking is how quickly should they come along or am I doing something wrong. Thanks
