Hi, Eddy I believe there is a Link on the website that tells you how to start your setup and Cycle- Once you begin mixing your salt adding your sand (if any) and LR
or Base rock- you would go to your local grocery store and pick up a couple large pieces of Raw Shrimp this will kick start your cycle and it should last awhile 2 to4 weeks is usually the norm just depends of your using like MB7 or adding LR
from an Established system. HTH
. Hopefully someone will come along with the Link.
