Throw in a piece of raw shrimp from the market.
Then wait (very, very patiently) for 6 to 8 weeks before you do anything else, other than testing the water.
You need 3 test kits, Ammonia, Nitrite and Nitrate.
The raw shrimp will begin to rot which will create ammonia
The ammonia will start the cycle and will feed the necessary bacteria
You will then start to see a rise in Nitrite and Ammonia will begin to drop off.
At about week 4 you should see Nitrates start to rise and ammonia and nitrite drop off.
Do NOT add any life to your tank until ammonia and nitrites read ZERO.
During this cycle period there is a good chance you will see green algae blooms, brown diatoms forming and reddish cyano bacteria blooms. This is NORMAL, do nothing, it will go away on its own.
