Just doing a bit of an experiment. My hypothesis is that Vermisol does not contain 2.36g of Levamisole per pill, based purely on the apparent difference in effect between the pure powder products and the Foye's dewormer tablet product.
1. Procedure.
Using a turkey baster, I applied approximately 10 newtons of force to the bulb, producing a stream from the open end of the implement of approximately 0.9 meters per second near the tip (JOKE). In any case, I blasted off my A. valida for a few seconds, and found that, yes, even after my second treatment with 24 pills of 23.6mg vermisol (for 34g. est. tank volume) the aefw's just laughed. So I recovered one of the little buggers. I placed it in 1/4 cup tank water at 11:00pm. I then added 0.125 (1/8) pill of Vermisol, waited approximately 30 seconds for it to disintegrate and stirred vigorously.
So, 1/8 tablet = 0.0236g/8 or 0.00295g. The total water volume is 1/4 cup, so: 16 cups per gallon, so to figure a quarter cup in gallons, it's 0.25 cups / 16cups/gal = 0.015625 gallons.
So my total dosage in this experiment (going by the initial protocol laid out in the second post of this thread) would be 5/300x0.015625 = 2.6x10^-4 or 0.00026g. for a proper dosage. To figure number of pills (again, for proper dosage) it's 0.00026g./0.0236g./pill = a whopping 0.011 pills. I put in approximately 0.125 of a pill, so the dosage I gave the aefw is approximately 11.4 times greater than the recommended dose.
2. Results.
The friggin' thing is still alive! It's been 41 minutes so far. Still cruzing the glass of the cup.
3. Discussion/Preliminary Findings.
Foye's Vermisol brand pigeon dewormer does not appear to contain 2.36g of Levamisol as advertised on the label of the bottle.
