Just curious if this looks like a new head forming or no? Duncan has been in tank for a few weeks and came from a large colony. Just saw this start to form a few days ago.
Ca 450 dkh 8.7 ph 8.1 nitrates 5 ppm. Ammonia. .25 ppm. I think that is wrong due to an api test kit being used for ammonia. And nitrates. Right now thats all im testing for.
