Due to a German website, this product contains: (1) 6.3 mg
Ethacridine lactate, (2) 3.2 mg Copper ++, (3) 0.26 mg Methyl

product. Be careful if you have certain plants because of (1), (2),
or if you have snails, shrimps because of (2).

I too would love to know what's in it, because it seems to be
all I need unless there is something specific (like eye fluke)
which needs specific treatment.
It is a sort of browny colour - almost blood red like iron.

I've scanned the leaflet, it's very crumpled (sorry!) but if
anyone is interested this is what it says in the packaging:

Hope that's some help?

It seems to claim to do almost everything from reading the
leaflet....I'm also curious as to what is in there...

Since Jürgen already posted the ingredients, I assume you want more
explanation?

1) Ethacridine lactate, marked in the 1920s as Rivanol, is an
antibacterial acridine. It is sometimes used to treat shigella.
2) Proflavin is another acridine that is very closely related to
acriflavin. It's good for killing protozoans like velvet, gram positive
bacteria, and fungus.
3) Copper is also good for killing protozoans like ich and velvet.
Works best but is most toxic to fish in soft water.
4) Methyl orange, good for??? It's normally used as a pH indicator in
aquarium alkalinity test kits. I've never seen it mentioned as a fish
medicine.

This is an antibiotic-free "scattershot" medicine, and it is reasonable
to try it for anything in the leaflet. It will have the strongest
action against protozoans like velvet, tetrahymena, and possibly ich. I
assume by blocking NTD they mean that it kills free-swimming parasites.
It would not stop transmission from scavenging infected corpses. I
wouldn't expect much for dropsy - these compounds don't penetrate tissue
every well so they wouldn't get inside the fish.

TetraMedica General Tonic is a similar mixture of acridines with
methylene blue and no copper. If you don't like copper, it's a good choice.

As for plants, proflavin must be safer. Acriflavine (a mixture of
acriflavin and proflavin) kills them quite effectively. The methylene
blue in the Tetra medicine also kills plants, but it's a pretty good
antifungal and antibacterial.
