I had set up my 25 gallon a couple weeks ago, and when I tested the water I had 0 ammonia, 0.1 nitrites and I can't quite remember the nitrates, so I added my DG. Then the other day I bought few guppies and put them in, and last night I noticed 2 of them have died. I tested the water again and its still 0 ammonia, but its between 0.3-0.8 nitrites and 10 nitrates :S. So I'm thinking that maybe the nitrogen cycle hasnt quite finished, should I wait to replace the fish until there's 0 nitrites? there's still a DG and a couple guppies left but I am going to return the guppies anyways, if they live, to get platies but I don't want them to die too. My DG is basically indestructable i think cuz he's lived through quite a lot (my roomate kept him in a measuring cup for 1 week before I rescued him, and put him in an uncycled 10 gallon, didnt not about the nitrogen cycle yet). Anyways I'm not sure if the guppies died from the tank not being cycled, or adding too many at once, or maybe from the other fish. one of the females had an injured fin and couldnt swim very well to begin with.
