discus still dark

[alan j t]

most of the time my fish are dark
i assumed one of my fish had worms so i dosed the whole tank
did the treatment twice as instructed on the directions
nothings changed as in plants or fish water change is every 3 days
water is as follows
ph 6.4 6.5
temp 84
nitrate 15 20
nitrite 0
i was thinking to bump up the temp and some salt
what i ve picked up reading this forum
but im afraid the tetras and cory cats might not handle it
i was considering metro but i dont want to get hasty
any ideas besides more heat and salt :?:
what other problems could it be :?:
im sur im acting paranoid
i guess im still considered a discus :newbie

salt will be much genteler on your scaless fish them metro, a few members have wiped out their bn's commons and peps with metro.

if the stools are white, you'll have to use it, use a seperate tank, and keep them there till their color is normal and they are putting back on weight till you put them back in the comunity tank.

ive bumb the temp up and salt and 50% w\c every other day
they look better and alot less shy
the smallest one is still getting beat up his fins arent looking to hot
a bit torn you could say
i have another tank50 gl plexi with bunch o plants and tetras
well established
would it be ok to put the runt in there until hes gets well
i know they are supposed to in schools but for now or
maybe i can convince the wife to get some more discus to keep him company
