Thanks for the post

There is no difference between the products, except in the dosing instructions. You need much less Prime in a pond due to the difference in it being an open system rather than a closed one. You can use Pond Prime in your aquariums; however, you will want to use the dosing for an aquarium system (1mL per 10 gallons or 2 drops per gallon) rather than a pond system (2 tablespoons for each 600-700 gallons).
