<Will this work with the fw's that lay eggs?
<Also, how do you measure out 40 ppm?
Yes, it will work for the egg laying flatworm.
To calculate drug dose use the following formula:
For 100% active drug:
volume in liters of tank x ppm (drug dosage) / 1000mg/g=#of grams required of the drug
For drugs that have less than 100% active drug, you take the percentage of the active drug (Levamisole hydrochloride is 80% active w/ 20% inert ingredients) and multiply the percentage to the 1000mg/g. So...
volume in L x ppm / 800mg/g = grams of drug
So if your treating a 10 gal tank w/ 40ppm Levamisole its:
37.8L x 40ppm / 800mg/g= 1.89g of Levamisole
Keep in mind, I'm not a vet, I just play one on TV.
