The Blue Shark team has more experience producing and distributing true nitrifying bacteria than anyone else.  That’s why Colony is the most used and trusted tank cycling produt on Earth.

Colony establishes nitrification in days instead of weeks.

True Nitrifying Bacteria: The Real Thing

Only aerobic autotrophs perform effective bio-filtration of toxic ammonia and nitrite. Having a very slow growth rate, a wait of 6-8 weeks may be required to establish bio-filtration in a new aquarium (aquarium cycling).

Colony effectively speeds up this process by introducing millions of these bacteria all at once.

Patience is a virtue in the aquarium hobby, but not at the expense of an education.  Colony also provides the foundation in understanding bio-filtration for the long run so that you’re always in control of it.

Use 

• To rapidly establish bio-filtration in new aquariums
• After medicating
• When adding new livestock
• Replacing media
