Ongoing care after the aquarium is cycled: To provide ongoing biological stability to a cycled aquarium: Switch to MicroBacter Clean after tank is fully cycled and one week has elapsed. This will greatly reduce problems during the "ugly stage." At that point, you can add Reef BioFuel to provide a carbon source for the MicroBacter Clean, if desired. If you want to switch to MicroBacter 7 the best time will be when the aquarium has been running for 4 to 6 months.
