Woke up this morning to my Tetra’s tank covered in ich again! Leaving for a week vacation in 2 days. All I can do is kick temp back up to 86F, add aquarium salt and leave it on its own while I’m away. I wish I had never bought all of these neon tetras! I’ve done all I can do. Poor cories are back in salt again. Dang, dang, dang it!
