The treatment is malachite green, which I gather will degrade in light, but
unsure of how long.

Also thought of using salt, but it may kill plants, so tried the chemical
first.

if the ich treatment has copper sulfate in it, then it is one treatment
cause it
doesnt inactivate... has to be removed by water changes or charcoal.
normally, quick cure is used every other day 3 times with 30% water
changes on teh
day the med isnt added.
what are your water quality parameters, ammonia, nitrites, nitrates and
pH?
change water, add 1 teaspoon salt per 5 gallons, no additives, dissolve
first, add
slowly.

sudden drop in temp by more than 4oF will bring on ich. as will poor water
quality.

Hi all, I am new at this, so would appreciate some advice.

I had a new tank set up: 10 gal, undergravel filter, a bunch of hornwort
&
2 small (1") fantails.

I had the tank running for a week before adding the plants, then the fish
2
days later.

On Day 4 after introducing the fish, I did a 30% water change, that's
when I
noticed the ICH. The fish were covered head to tail with white spots. I
ran out & got some Clear Ick (Jungle), and treated the tank. 36 hrs
later,
the spots are gone, except for maybe one in the tail fin.

Although the label says treat once & forget (and maybe a second treatment
if
needed), from reading about this, ICH can survive for a long time as
cyst,
so I am a bit sceptical.

To be sure, I did a 25% water change 48 hrs after treatment, and added
more
medicine (to make up for the new water).

The fish are fine (actually, they showed no signs of distress at any
time),
and I am now wondering how long to keep the Ich meds in the tank.

From reading the tropical fish news/web sites, I gathered that the cysts
should be gone 2-3 days after they disappear from the fish, but they all
say
that at lower temperature, the cycle can be much longer.

So the question is: How long to keep up the treatment so as to irradiate
the
pests once & for all? BTW, my tank temp is around 70-75 F (we are having
a
heat wave!).

Thanks in advance.

JS.
