Measurement Question-Super Aquarium Purifier

[damsel dame]

Could someone answer a measuerment question? I bought a product called Super Aquarium Purifier made by Aquarium Systems and it says to add 1 unit of the product into a mesh bag. Could someone tell me what a unit is????

Have you opened the container? These things sometimes come pre-measured. It should be obvious. If not, there is usually a phone number on salt water products in case you have problems or questions.
