Or check their website -- tons of great info there, including dosing instructions:

It does look like the pond version is a higher concentration (I missed that earlier); they recommend 1 cup per 1200g of the pond version vs. 1 cup per 480g for the aquarium version. Kordon is great in that all their aquarium chemicals use the exact same dosage: 1 capful (5 ml) per 10g of water. Since it looks like the pond version is about 3x as strong, you'd probably be safer cutting the dosage to 1 capful per 30g.
