I have been attempting to cycle my tank now for 6-7 weeks, I use Prime to treat the water as my water company only uses chloramine (the tap has a reading of ~2 ppm), and keep getting high readings (2 - 4 ppm). I found out tonight that Prime (or any other de-chlorinater) will still test positive with the API test kit, so I will always have a positive result. So how am I supposed to know when the tank is cycled? How can I be sure I have enough bacteria to handle the ammonia produced by 4 (less than 1 inch fantails) in a 40 gal breeder? I already worry that one has ammonia burns from being in the quarantine tank too long (even with daily water changes). He has black smudges in some areas of his body that weren't there when I bought him, the scales in those areas seem intact. Though he shows now sign of discomfort, redness, swelling, eats great...Also, if one had burns, wouldn't they all? One is pure white and has been without blemish for 4 weeks. I need to get the fish out of the quarantine tank as soon as possible (it also tests positive, between 0.25 and 1 ppm even with daily water changes - but also using Prime), but I don't want to kill them now that the quarantine is finally done.
