It's hard to judge colors over the internet, but I'd say you're interpretation of about 0.5 ppm ammonia looks about right. It should lighten up a little more towards yellow.That’s great to hear. Thanks for the reply. Just so I understand, once the ammonia reads .25 I should be able to add a fish? I was planning on going to a fish store this weekend. I don’t have one locally so I have to drive an hour and a half so I wanna make sure it’s safe to add a fish. I’m not gonna go wild. Just gonna get something to keep things going.
The reason I say 0.25, is because to some peoples' eyes, when the result is zero, it will still have a slight green tint to it.
I would bet you'll be okay to add a small fish by the weekend, but I would trust your own eyes and trust your kit.
I would not add coral to a 10 day old tank.
