Questions about Ich
 

Does anyone really know:
Can Ich survive in an aquarium with no fish, no living animals?
I've have a 40 gal tank that my kids use.
Two months ago they bought some fish, loaches, tetras, etc.
Within 5 days I noticed Ich.
Tried to treat it with Quick Cure.
Didn't work and all fish soon died.
Changed out filter but did not change water.
Let tank run for about 6 weeks.
Kids then went and bought 5-6 Platy's and I noticed about 3-4 days later
that fish had Ich.
I've read a ton about Ich in the last day, I am actually overloaded on the
topic.
Raise your tank water temp to 87-90 degrees. Add salt. Do this, don't do
this.

Not likely.

That kind of a long time with no bio-load, you might have lost the
bacteria which handle your fish waste. You might need to go through the
process of cycling your tank again... (dunno, your first fish load may
not have been cycled, either).

Kids then went and bought 5-6 Platy's and I noticed about 3-4 days
later that fish had Ich.

They might have gotten stressed in an un-cycled tank. I'm told that
livebearers aren't the best thing in the world to cycle a tank with (not
a livebearer fan, myself). What are your water parameters, esp.
ammonia, nitrite and nitrate?

Let's assume you've cycled the tank, the above is not relevant, and your
water parameters are good (ammonia zero, nitrites zero, nitrates 40
mg/L);
When treating with a copper-derived medication, you have to
discontinue carbon filtration, if you have it. Carbon will suck the
medication out of the water lickety-split, before it can act on the
ich...
What is your treatment cycle? I go with four treatments, spaced four
days apart, with a 50% water change before each treatment is added to
the tank. That way, you hae the whole life-span of the ich covered.

Yeah, the extra heat is often suggested, I've done it with some cardinal
tetras in the last year. Does anyone know if the platies would have a
particular issue with temps this high? Not knowing the breed, I'd tend
to keep the water temperature at the optimum for the species, as that
will tend to stress the fish less. All that the extra heat ultimately
does is reduce the total number of tomites, and speed up the total life
cycle of the ich a bit. Not an acceptable trade-off, IMO against the
extra stress on the fish, unless the specific fish can also handle those
higher temps (for cardinal tetras and bettas, no problem).

Sorry to hear about your tough time with the ich. Hope you can sort it
out...

Were there fish living happily in that tank before the additions? If
there weren't then you need to cycle your tank.

Ich need new hosts to survive. You can guarantee that ich will be dead
by 6 weeks, if not by 3 weeks.

Can Ich survive in an aquarium with no fish, no living animals?

Ich can survive as a free swimming swarmer cell for about 48 hours. If
it does not find a host in that time period it will die. Ich can
survive as a multiplying mother cell in the substrate (or wherever it
lands) for approximately the same amount of time (depending on a few
variables including temperature and how engorged the mother cell was
before it left the host).

Ich medications are only effective against the free swimming swarmer
cell, not the infected Ich cyst or the mother cell stage.

If your tank is absent of fish for 4 to 7 days you can consider it Ich
free.

Ich is a relatively weak parasite and it is often the case that many
fish spend much of the lifetime hosting a latent Ich infestation.
Loaches, especially wild caught ones, are notorious for this.

A healthy fish can resist a mild Ich infestation to the point of
manifesting no visible symptoms. If the fish is subjected to stress
(e.g. due to transport or inappropriate tank or water conditions) the
immune system can fail and Ich can break-out manifesting itself as the
obvious and common white-spot disease. When a break-out occurs there
will be so many swarmer cells appearing in a very concentrated
environment that even a healthy fish will often not be able to fight off
the parasitic assault effectively.

Chances are the fish you are buying are hosting a latent infection
before they ever enter your tank. I would suggest you check your water
conditions before adding new fish and consider finding a new supplier or
at the very least quarantine your new fish and treat them for three days
with QuickCure before introducing them to your aquarium.

You said that your first Ich treatment with Quick Cure didn't work and
all the fish died.
This really puzzles me, as QC is the best medicine (IMO) for Ich there
is (not to mention a ton of other "nasties" it kills that the bottle
doesn't list).
I have to ask....
Was the carbon removed from the filter system?
Was the QC bought new for this treatment, or had it been previously
opened and sat on a shelf somewhere?

Oh...always after treating with meds you should do a partial water
change.
You mentioned changing out the filter pad, but not changing any water.
Why is that?
Water changes are the best thing you can do for your tank.
Keep a regular schedule, and do an extra one after medication.
When ever your fish have or even don't have obvious symptoms, or have
J.A.R. (just aint right), do a water change!

QuickCure is great for eliminating Ich in its free-swimming stage, but it
is not magic. I have seen a number of sick fish resist treatment and
succumb to the infestation anyway. A successful treatment is not only
based on proper dosing, but also on the quality of the environment, as well
as the level of stress and overall health of the affected fish.

For example, I recently witnessed a single platinum angelfish resist
treatment for Ich using QuickCure while all other angels in the tank showed
no signs of infestation after the second day of treatment. This particular
angel was being picked on by the remaining healthy angels and the resulting
stress caused by these assaults no doubt lowered the animals immune
response. It is also possible this particular angel may have had a genetic
abnormality in its immune function given the amount of inbreeding required
to produce a platinum angelfish (one out of every ten or so platinum angels
are so genetically warped that they never even develop ventral fins).

Some swarmer cells may survive treatment with QuickCure, under ideal
conditions the number of free-swimming swarmers is reduced significantly
enough to allow a strong fish to easily resist the remaining parasites, but
it is not always the case that a fish is in the proper condition to do so.
Since the original poster appeared to be experiencing an outbreak in a
brand-new tank, it is likely nitrogenous wastes were playing a role in the
stress and death of the infested fish. Ich on its own is rarely enough to
kill a healthy animal unless the disease is allowed to progress to a
ridiculous degree.

QuickCure has an extremely long shelf life. We buy it in bulk in large
gallon jugs that last several years.

I'll have to disagree with you about Quick Cure being magic.
As long as you treat for a full week. I know it only says 3 days on the
bottle, but we all know the cycle of Ich is longer than 3 days. Treat
for a week and the Ich is gone like magic. = )
As for Q.C. having a long shelf life, I believe it was one of the regs
here that said it after it was opened it had a shorter lifespan.
The only time I've had no luck with Q.C. was on a Clown Loach. I used a
half dose (done this before with good results) and nothing. The Loach
died from such a bad infestation.
However, I was told at that time here that it was possible the Q.C. was
old.
I said it had been opened and sitting there for near 2 yrs I think.
I was then told it was probably old and not useful anymore.
So....who's the answers on Qucik Cure's shelf life?
As in from the manufactor?

Have you ever tried heat and salt for ick on Clown Loaches? Did it work?
