I've never seen it in pet store or mail order ads. I got
some from a local chemical supplier.
Be careful with it and use gloves - it will stain your skin.
If you use it for dips, a few tiny crystals in a gallon of
water are all you need to make the water pinkish.
Some plants, like Valisneria, are sensitive to it.

I saw your message yesterday (7/5) and, since I am new to this .newsrch
newsgroup, I thought I could kill two birds with one stone. First, I
could work through this by reading and responding to test my prowess!
Second, I could provide some real help. So here goes the help: I have a
copy of a book written by one of the real "old gods" of aquaria, William
T. Innes who, in 1952, wrote "Exotic Aquarium Fishes: A Work of General
Reference", which for many years after that was the bible for fish
fanciers. I got this copy when I was a young boy for a birthday
present. I knew he had something authoritative to say about permangante
and here it is from page 47: Permanganate of Potash - Like salt, this
drug has many uses. Although marked "poison" by druggists, there is no
danger in using it in moderation. Physicians have prescribed it, in weak
solution, as an astringent gargle, and even as a nasal douche. Its uses
in the aquarium remind one of the multiple claims on bottles of patent
medicines. At a strength of 1/8 grain-to-the-gallon" (by which, I think he
means 125mg), "it is perfectly safe for temporarily clearing green water,
or as a mild antiseptic in treating fungus diseases and some of the
parasitic ones. For the latter, or for a safe sterilizing bath, hold the
fish in a net and dip it for a full minute into a quart of water into
which one grain (by weight)" (one gram) "has been freshly dissolved.
This oxydizing drug has the advantage that in the presence of organic
matter it soon exhausts itself; and that its effects are not cumulative.
Mild doses may be repeated, after the magenta and the following yellowish
color disappears, without building up concentration. Crystal
permanganate of potash at photographic suply houses is cheap, or it may
be had in convenient measured grain tablets from druggists."
So, you have now heard from the "god" himself! It is really amazing how,
in those days, forty odd years ago, you used what was available and they
all worked. For instance, besides permanaganate, mercurochrome and
methylene blue were used for ich, fungus, etc.
I hope this has been of some help to you.

In [an earlier post in this thread - Editor], a
grain is claimed to be the same as a gram. Actually, a grain is about
64.8 mg, so the article is off by a factor of 15. This may cause
problems, since the discussion is about how much potassium permanganate
to use in a fish tank.

Potassium permanganate will kill everything, it is a strong bleach.
Here is something that APD'ers may find useful in this topic:
Potassium permanganate's potency increases when it is acidified,
add a little dilute sulphuric acid to the solution.
After you apply Potassium permanganate, you will find everything stained brown.
To remove the stain apply a solution sodium metabilsulphite, this chemical is a food
available here in grocery stores. The stain disappears like *magic*.
