Hello friends and experts (not mutually exclusive),
On 2 May I placed my blue and yellow tangs in copper treatment. By 5 may I thought I was at a therapeutic dose of .5ppm (cupramine). Turned out to be a testing error and was only .4 so I'm only confident I was at therapeutic .5 from 12 may.
All signs of ich (it was only mild) disappeared in the first couple of days. I've looked again today and the blue tang has a small number of spots again. Technically I'm 2 weeks and 3 days in at .5 ppm.
Is this normal? Is this ich that was in a tomont stage before I was at a therapeutic dose and now in the trophont stage?
