    i just checked my ammonia yesterday and it turned out 0.5mg/l. is that a bad sign? i did 20% water change, but not sure if it is enough

    20% water change only would bring down your ammonia to 0.4.

    Is this tank an established tank...?

    yes it is. but i think i fed like too much recently. therefore the spike in ammonia. so will the ammonia go down slowly or must i change more water?
