RidIck is a mixture of formalin and malachite green. It will kill filters,
so care must be exercised to remove filtration during treatment or turn off
filters. It is also heavier than water, so without some form of mixing, it
will create high concentrations at the bottom that can kill fish. Formalin
should not be left in the pond, but concentration reduced at about 2 hours
after dosing, by doing a 50% water change. Salt is non-toxic to the
filters, at least in the dosages that you would use to treat fish.

The filter media in the large pond will survive for a few days on the waste
that is already in the pond, but may slow down due to a lack of supply of
food. As soon as treatments have concluded, move some of the fish back, and
monitor ammonia and nitrites.

Maybe the koi are tougher than the GF? It's the GF that showed signs of
ich but
it was after the purchase of the koi from the feeder tank. The new and
older
koi look ok.

I've been using Rid Ich along with salt. I don't have the test kit or a
thermometer yet so I don't know exactly how much salt is in there or the
temperature.

It's probably too late now but will Rid Ich kill the bio filter? What
about
salt?

Will the bio thingys stay alive in the bigger pond that now has no fish?
I
moved all the fish to my smaller pond so I would use less of the Rid Ich?

This is all really frustrating! I do appreciate all of the different
ideas
and advice form you all!

Thanks, Judi

Ich doesn't present on koi like goldfish usually. On goldfish it will
look
like grains of salt, but koi don't aways show this. If the white spots
are
bigger than a grain, you've got something else going on. The safest
thing
you can treat with is salt, regardless, get it up to 0.3%. You need to
be
watching your water chemistry. I highly suggest you use that gift
certificate on test kits as others have suggested. I know we've already
covered how to add & use the salt in other threads for you.

If indeed you need other medications, there are better ones out there
that
don't kill the bio-filter, that PetsMart doesn't carry. ~ jan


From:

on koi it looks like a bad red rash and their fins are clamped. salt may
work, but
the only other way to treat this right now unless you can bring em
inside. PP
can
work on other stuff outside in the pond. I see some oodinium on my koi,
but
it
disappears quickly when the temp got up to 55oF.
what is the temp of your pond water? ingrid

At the end of last summer I bought some baby koi out of the feeder
tanks at
Pet
Smart. Along with the koi came lots of parasites(ich, anchor worms,
etc.).
I
brought the fish inside for about 3 wks. until it looked like the
parasites
were gone. They were fine all winter until last week when the
temperatures
rose. (I'm in Bakersfield, CA). Anyway, there are already new signs of
ich!
Since I've been reading posts on this site regarding salt, the use of
salt
and
parasites, I'm not really sure what to do now. Do I use meds with salt?
Will
salt really kill ich? Should I start treating now or wait until it's
warmer?
Should I net the fish with spots and give them salt dips? Thanks for
your
help.
