I had a flame angel that I bought, that I believe had Ick or velvet. It has since died, so I started treating my tank because I noticed white spots on my blue throat. I'm on day 3 of the treatment. I also noticed spots on my sailfin. My dilemma is I did some plumbing work on the tank over the weekend, and I started thinking could the fumes from the PVC cement have caused some problems in my tank too. So I'm not sure how to go about solving for this. Any help would be great.
