I read and did a lot of research about it and people say that the temp should be raised to 86 F and salt should be added until salinity is 0.3%... but I have a couple of questions... right now my tank is at 85-87 F, I haven't added any salt yet but my goldfish look horrible... they aren't gasping for air at the top as my tank is aerated very well but I can clearly see a lot of red veins in their fins. I don't know if they can handle the high temp for the entire treatment. Also, I have a couple of plants in my tank, will they die if I add the salt? and can I just use the salt I have in the kitchen? I'm pretty sure it has some iodine in it. I just have anacharis and anubias in the tank.
