FAQ:

Q: What happens when you add fresh water to a Sea Monkey tank?

A: Sea-Monkeys adapt well to the gradual process of their water world becoming more salty as the water level drops. However, replenishing the water can be a shock to their system as the salt concentration quickly changes when fresh water is added back to their tank.

Q: What’s the best way to make Sea Monkeys?

A: Pour water at room temperature – 27º C. (76º F.). Cut open packet #1 “Water Purifier”, pour the entire contents into the water and stir. Let it sit for 24 hours away from excess sun or cold. 24 hours later, cut open packet #2 “Instant Live Eggs”, add contents to water and stir for one minute.

Q: Can a Sea Monkey swim with an air pump?

A: Caution: A high power air pump may cause too much motion in the water. Make sure your Sea-Monkey pets are able to swim freely and are not being violently tossed around by an extreme air flow.

Q: How often should I aerate my Sea Monkey tank?

A: If there is too much carbonic acid present in your tank, Sea-Monkeys cannot make use of the oxygen that is available to them. As a result, they suffocate. So for the best results (and as a precautionary measure), aerate on a daily basis the first week.
