Help sick guppy

Cross posting with alt.aquaria

I have a female guppy who this morning appears to have a loose scaley
appearance. Early form of Cotton? This looks like her scales are sticking
up and sort of fuzzy, she also has fuzzy spots on her front fins. Her back
tail has a couple white specks. The only thing I have in the house is Rid
Ich, I just removed my plants from the tank and put a dose in and pulled out
my carbon and raised the temperature a bit. Do you think this is a good
start for treatment? I do not have any Epsom or aquarium salt in the house
for a salt bath as that was my next approach. By the way, when they say to
do a Salt Bath, exactly what do you do? By the way, she is in with 3 other
guppies and 2 albino cats, and no, I do not have a hospital tank to move her
to, though I know I should.

Any ideas?
