Praziquantel measurements

[NC2WA]

Lee,

I am getting a Praziquantel product to put on my frozen food for the new fish that are in my QT tanks.

here are the instructions:

"To each 100 grams (3.5 oz) of dry feed (flake, granular, or pelleted) thoroughly mix in 400 mg of Microbe-Lift Praziquantel."

My problem is I am not finding a directly conversion of Mg to teaspoon or tablespoon so I can sprinkle it on the food. I don't want to overdose the fish.

Can you help or any idea where I can find a thorough conversion chart?

thx
Kirk

Sounds like those instructions are for adding it to pond fish feed. This instruction doesn't care how much the fish eats. So a fish that eats more, gets more med. My instruction for feeding is a certain amount of med depending upon the weight of the fish. Anyway. . .One problem is that mg is so small that it doesn't' relate to a teaspoon or Tablespoon. Kind of a like comparing an ant to an elephant. Adding to the problem is that milligram is a weight (mass) measurement and teaspoon-Tablespoon is a volume measurement. Then the next complication is going metric to American Standard. Sort of like of how many pounds in a liter of water. Still, we know the 'weight' of water as it compares to its volume, and so we have the ol' standby - a pint a pound the world 'round.

Having bored you by now, I'll say this: 400mg = 0.4 grams. There are about 28.35 grams in one ounce. Now we know how ounces compare to volume: One teaspoon is 0.1667 ounces. (It takes 3 teaspoons to get to about half an ounce, which is. . .14.2 grams). There are many converters for this. So. . .

0.4g = about 0.0141 ounces. 0.0141 ounces = about 0.00235 of a teaspoon. So now you might see how we're talking ants and elephants. I don't know of any conversion for this because of the 'four' mixing scales (metric, American Standard, volume, and weight).

You probably should just stick with the ratio: 0.4/100 is the addition ratio. For every "100 parts of the dry food" you're putting in "0.4 parts of the med." You can play with this. Take the amount of dry food in your feeding. Mentally divide it into 100 parts and then add half of one of those imaginary parts of the med. It gets more tricky with wet, frozen, high density food and the med which might be a powder. In the latter case, if the med is pure Praziquantel, I'd just use the suggested eyeball measurement I suggested in the de-worming post.

Lee,

thanks..while i was waiting for you reply, I was reading on the Internet that mg and teaspoons are not the same (the ant vs elephant analogy you use), so I might be using the good 'ol eye ball method.
