No problem I've been searching the net the last 5 days and I saw both as well so I was confused.
Finally some good news today. The salt has been working. It wasnt enough when I was using 1 tbsp per 10 gallons but after u guys recommended 5 cups for the 75 gallons and temps up to 88 I'm starting to see a difference. I'll continue with salt and heat with aged water changes for the next few days. Furan 2 will be here tomorrow so I'll have that on hand just in case anything happens.
2 of the discus still arent eatting tho
