I've had my 5 loaches for about 15 months now. I originally got them to
control snail population. I recently bought the Hagen CO2 system, and my pH
has dropped to 6.6 (from 7.6). The temp is at 84C (there are 2 discus in
the tank). kH is low at 1.8.

Suddenly, the clowns have ich. I'm treating using Clout at one-half the
recommended dosage. Is there anything I should be aware of? There are also
3 ottos and 2 corys in the tank.

At this small dosage, is it possible to cure the ich without harming my
loaches? I've got enough clout to dose for 10 days, and will buy more if
necessary. I don't really want to kill any plants either (well, hornwart
and duckweed could go to h*ll)

I realize the bioload is high in my tank, but it hasn't been a problem since
I drip water into the tank each day to what amounts to a 25 % change daily.

Thanks in advance for any ideas.
