I found a source for Levamisol HCL at a local feed store and was able to purchase a single horse (Sheep) pill (1.8G) for a dollar, under the name "Tramisol". My question is, what is the recommended dosage for a 55 gallon tank, and how should the substance be introduced to the water? >>>>> White stringy feces are typically a sign of Hexamita or Spironucleus infection, although other causes can not be excluded completely. Levamisole is not active on these flagellate parasites. The most appropriate first-line treatment in your case is in my opinion metronidazole, either as a 250 mg capsule/10 gal every other day for three times, or as Tetra flakes for parasites (not those for bacteria!) used for about a week. Typically these parasites are hard to eliminate, but treatment will reduce their number at least for several weeks or months. If you see no response at all, you can then suspect nematodes, and use the levamisole. I do not have the dosing data for your formulation at this time, but if you need it I can see what I have at home. Just let me know.
