I'm on day 20 of a fishless cycle for my 5 gallon tank, and I've got a question. The water is starting to appear a slight bit foggy and has been for a few days. This'll probably sound odd, but it looks the way water would if you had drank a glass of milk, then filled the glass back up with water - just very very slightly foggy white. At this stage in our cycle the nitrates have begun to show and have risen to a level of 1 ppm. The water has not been changed or disturbed since the beginning of the cycle, and nothing new has been added to the tank except ammonia to keep feeding the cycling process.
Does anyone know if I should be concerned about this, or if this is just par for the course? Any idea what I should do if it is something to be concerned about? Thanks again, very excited to have my betta's new home all finished!
