Levamisole can be added to the diet at 0.1% of the amount and fed for 7 days for removal of nematodes.
So if you used one pound of food – you’d want 450mg to 500mg of Levamisole in that food. Or, ON IT – you can crush up Levamisole and put it ON a food using confectioner’s glaze. (Large amounts of medicated food, and How To Use Confectioner’s Glaze to Make Medicated Food)
Tramisol Levamisol for Worms in Koi
Levamisole (Tramisol) – by Doc Johnson
As a water additive, Levamisole Phosphate can be used effectively as a dewormer for Goldfish and Koi, among other species, as an indefinite and safe treatment. The dosage is 0.5 ppm (zero- point-five PPM) added directly to the system without impediment to the filter or fish.
Here is a source of Levamisole.
Levamisole / Tramisol will NOT KILL FLUKES
It’s used for a particular fluke of MAMMALS – and that’s *not* a fish-fluke.
“Almost any veterinarian can and will get Tramisol if you ask nicely.” ~ Doc Johnson
Meaasuring the dry Levamisole? Easy and it’s less than fifteen bucks. A nice gram scale is cheap on Amazon.

Here as promised is the recipe for Camallanus treatment.1. Add 1.5 milliliter per 7.5 liter of 7.5% Levacide (levamisole hydrochloride) to each tanks to be treatedMix the drug in a liter of water before pouring over the tank surface. If you obtain another strength ofthe drug (e.g. 1.5%, 3%) then just adjust dosage as required. For example: If you got 1.5% add 1 ml in 1.5L of tank water.2. After 24 hours perform 100% (as much as possible) water change whilst vacuurning the gravel. Thewater change is not required due to toxicity but to remove the possibility any offspring in the gravel.3. No further treatments should be necessaryGood luck and please let me know how you get on. Feel free to pass this information to whoever youlike.Regards, Ken L”
