Ich

[Sake]

Had a bit of a scare last night! So i figured since it had been a bit since i really gave my tank a good vacuum, I would move all my decorations and do a nice deep clean. Since the ich spots are completely gone figured it would be a good idea. Well did a 75-80% water change, deep clean, and refilled the tank no big deal right? Wrong next thing I know one of my neon tetras is sluggish, few minutes later he's laying on his side on top of some plants. Now i know I added chlorine remover to the tank, so that shouldn't be the problem...but did I add enough? I dropped the measuring cap into the tank and had to fish it out. Not sure if I put the full dose in, so i just put enough to treat another 30 gallons and this morning he's swimming around and schooling with the rest
