just tested water with the API kit
Ammonia 0, nitrite 0, but nitrate on 4
Should I do a part water change or leave it and test again in couple of days fish seem happy enough got 12 tetras altogether in a 60 litre tank
And 2 live plants at the moment
Nitrates or 4ppm or 40ppm? If the former, you're fine and no water change is really necessary. If the latter, I would do at least 50%.

A nice water change can't hurt the only thing that will hurt is the pain when your fish die to bad water quality. (I'm exaggerating), but seriously a water change will only make the fish happier.

40 nitrates is at the upper limit of what you want to see. Once nitrates begin showing red or dark orange on the test kit, a water change should be performed. More live plants will help keep nitrates under control between weekly water changes (especially floating plants). Watch how much you feed, don't overstock, and try to aim for 20ppm nitrates or less.
