I have a discus that turned black. I have been advised to use table salt. I have 29 gallons so I should put 29 tablespoon. Should I dissolve the salt before I put in the aquarium? If I continue to use the salt forever would I kill them in the long run?
Also when I make a water change would I need the water be the same temperature of the aquarium or can I put in cooler? Temp is about 29C and the new water would be around 20C.
Thank you
