Fish-less Cycling Program

What is the Fish-less Cycling Program © and how can I sign up?


IMPORTANT: This procedure is to be conducted without jellyfish or fish in your aquarium. It's the Fish-less Cycling Program©, meaning "without fish." Cycling an aquarium produces temporary spikes of ammonia and nitrite that are toxic and harmful to jellyfish and fish (any saltwater animal, really).

A fish-less cycle is the best and safest way to cycle your aquarium to ensure it is biologically stable and habitable for jellyfish. The goal of cycling a new tank is to establish a healthy and strong colony of beneficial bacteria in your filters to take care of waste that is created by feeding your jellyfish.

The Fish-less Cycling Program© involves placing a “pea” size (⅛” or 6mm) piece of raw shrimp into your filter box under the drip tray. If your aquarium does not have a filter box or drip tray, then you can place the piece of raw shrimp directly into your tank to decompose. 

The decomposing raw shrimp will begin to create ammonia and start the cycling process. As your system goes through the cycling process you will check in with us once a week with a picture of your API test readings and we will both record your findings.

This is open to all jellyfish aquarium owners, regardless of the type or brand of jellyfish tank you own. If you choose to participate in our Fish-less Cycling Program ©, you will receive 3 FREE moon jellyfish with your first order of jellyfish after completing the program successfully.  

PLEASE NOTE AGAIN, this is to be done before you have jellyfish in your tank!!!

***For new Eon owners:

If you just purchased an Eon Jellyfish System and sign up for the Fish-less Cycling Program © and complete it, you will receive 6 free moon jellyfish with your first order of jellyfish, along with the free frozen food offered with the Eon purchase.
