I have about freshwater dip too. Why & how would you do this? It seems like it could more cause stress. I have a parasite on my dogface pufferfish (on 1 of his fins). We have treating the tank with Coppersafe. I did the last treatment last night and it's still not off. How long could it take for the parasite to fall off him?

Our readings as of last night were:
ammonia is 0,
nitrite is 0,
nitrate is 80,
salinity is 1.021,
pH is 7.8,
alkalinity is 300
I tried to upload som photos so you could see what I'm talking about. The uploads failed twice.
