I recieved my measuring spoons I got from greg watsons site today. However, they are really weird. Instead of labeled in tablespoons or fractions or whatever, they are labeled Smidgen, which is the smallest, Pinch, which is the middle, and Dash which is the biggest. Does anyone else own these spoons and know what the actual measurements are? Which spoon should I use for what gallon tank. I have a 10 and a 30 and plan on dosing dry nitrates and phosphates.
