For your aquarium to safely be able to house inverts, fish and coral it must be cycled.  

Cycling is the process of establishing the bacteria that quickly breaks down fish waste and food into a less harmful matter 

FISH WASTE AND FOOD TURN TO AMMONIA 

Fish food and waste breaks down into ammonia which is very toxic to live animals 

BACTERIA TAKES AMMONIA TO NITRITE 

Specialized bacteria break down the ammonia turning it into nitrite which is less toxic than ammonia 

BACTERIA TAKES NITRITE TO NITRATE – REMOVED BY WATER CHANGES 

Another strain of bacteria breaks down nitrite to nitrate which is nontoxic except at high levels.  Nitrate is then removed through water changes 

BACTERIA MUST GROW IN A NEW AQUARIUM TO HIGH ENOUGH LEVEL 

During the cycle the bacteria that breaks down ammonia and nitrite must grow to a high enough population where ammonia is broken down all the way to nitrate quickly  

LIVE SAND/LIFE ROCK BENEFITS 

Adding CaribSea live sand and life rock introduces beneficial bacteria into the system right away. 

LIQUID BACTERIA 

We are also adding a liquid bacteria supplement to speed up the cycle process. 

NEED A WASTE SOURCE 

For any cycle to start you must have a waste product to break down into ammonia. 

FISHLESS CYCLE AND WHY 

We utilize a fishless cycle so that no live animals are harmed or stressed. In a fishless cycle you use fish food as the waste product instead of live fish.  Feed your aquarium every day or two a small amount of food 

TESTING WATER 

During your cycle you will need to test your water every few days to monitor ammonia, nitrite and nitrate levels 

DESIRED RESULTS 

Before adding any livestock to your aquarium ammonia and nitrite levels must be at 0 and nitrate should be under 20  

HOW LONG DOES IT TAKE? 

The length of the aquarium cycle process will depend on how much beneficial bacteria you already have established in the aquarium. 

CONTINUE TO ADD BACTERIA/NO LIGHTS 

During the cycle continue to add bacteria to the system.  It is not necessary or recommended to have your light on more than an hour or two a day while cycling.
