My second tank, has been running for about 2 weeks now(borrowed some gravel and balls from a well established tank). The readings are: Ammonia---1.0ppm (high I know, but read on), nitrites----.25ppm, and Nitrates----5ppm. While I thought these were odd readings, I redid them again and got the same thing...what's it look like to you guys? There are fish in the aquarium, so I know keep up with daily/semi-daily PWC.....
