I went through ick once on my 28g tropical. I squashed it using the temp raise + non iodized salt method. This morning I was checking out my 55 and I see many very tiny white spots on my ropefish and large adult cichlid. The others are unaffected. I assume this is ick. Is it safe to sue the temp raise/salt method with these guys? I also have some bichirs in this tank (see signature). Also, what concentration salt solution do you recommend?
