Alum USP is used to control and kill snails and microscopic bugs, such as water
flies on new live aquarium plants. It can be used as 1 hour dip or 48-72 hours soak.
Short term dip may kill adult snails, but will not kill eggs. Longer soaking is
recommended for killing snails eggs right after they hatch. Alum USP is
aluminum compound that is not so harsh on live plants, as cooper sulfate. Usage of
Alum USP is recommended in a separate container. Below you will find dosages
to prepare working solution volume of 1 gallon. For fewer plants – smaller volume
of solution may be required . For example: to prepare 1 quart of working solution,
All dosages that are used for making of 1 gallon must be divided by 4.
My packages are 1 ounce, which is equal to 30 grams.
Hey Mike, is this your receipe? If not, please post yours.
Alum Dip: (up to 1 hour)
The Alum dip is more for killing microscopic bugs. Use at 1 tablespoon per gallon of water. For snails and snail eggs a 2-3 hour soak in stronger solution of 3 tablespoons per gallon of water is a better choice.
Alum Soak:
Use 9-10 teaspoons (3 table spoons) to 1 gallon of water: soaks of 2 to 3 days are needed to kill snails and snail eggs.
