One dead fish a day HELP

[corper]

The water quality in the tank is good, just a little amonia from the dead fish. I have done a couple of water changes.

I was told to use nox-ich but am not a fan of the stuff my self. I'm trying to set up a sick tank for the fish but i'm not sure what to treat the fish with.

What do you mean let the tank go fallow?

The seaweed I purchased from a fish store. It is from ethier Indonesia or Fuji. I don't know the names of the two seaweeds though. I will take some pics and post them. Is it possible what I think is seaweed is really kelp?
