Hydra CATALYST SYSTEM

the technical protocol behind Fast Cycling.

Choose Catalyst System if you want to work directly with Catalyst One + Two to develop and validate the nitrogen cycle in a new aquarium without fauna.

The two parts provide the controlled load required for the development of the biofilter. must be used together.

It's for you if...

• You are cycling an aquarium without fauna
• Do you want to accompany ammonia, nitrite and nitrate through tests
• have filter and good oxygenation in operation

How to use — Reference for 100 L

add daily 5 ml Catalyst One + 5 ml Catalyst Two.

Do not introduce fauna during the process. It confirms the evolution through tests of ammonia and nitrite.

when does it end?

The cycle is functional when the biofilter manages to process the load and the tests confirm undetectable ammonia and nitrite. Don't just use the number of days as a criterion.

Do you want the simplest version to choose from?

hydra fast cycling presents this same concept as a starter solution. fast cycling pro Adds biocore for microbiological reinforcement.
