I've been doing water changes and the parameters are not changing. However, the colors on both the ammonia and nitrites seem to have lightened while the nitrate color darkened quite a bit. Is that possible with the API liquid test kit?
Anyway, I think there is a problem. Just now, I noticed white stuff clinging to the stocking covering the filter. It's also speckled in his gravel. Here are some pictures. What the heck is this, and what do I do? Ugg, sorry to be such a pain guys.
