I use potossium permanganate on occasion. A weak
solution can be used to kill invertebrates, as well as
oxidize dissolved organic matter in the water. I
think Jungle sells it as a water clearing agent (by
breaking down the dissolved organics). I have a
formula around somewhere for the tank strength
solution; I'll look for it. I use the powdered
*danger* variety from Home Depot, then dilute it. A
tiny $8 jug will last a lifetime, nay, two lifetimes.

Otherwise, I do agree that my gut reaction to the fish
scratching problem is a chemical in the water, such as
nitrates/ites or even a dissolved metal.

.....What did you use for potassium permanganate? That
stuff scares me around fish although I use it for
plant disinfecting...
