Before coming to this forum, I ventured on my own and bought a new tank. I've had them before many years ago. I setup about a week ago and went the fish cycling avenue using API Quick Start. It's been a week, I have 11 Tetras and they are doing well. My question is, I'm using an API test kit and I'm getting a 0 reading on ammonia, nitrite and nitrates every time I test, is this normal? Just curious as to why nothing is showing up. The fish are all small BTW. Thank you.
