ATM Colony Marine 32oz (946ml) Nitrifying Bacteria

Trusted by public aquariums all over the world, Colony is the standard when it comes to establishing biological filtration and aquariums.

Before adding livestock, a colony of beneficial bacteria should be established in the aquarium and biological filter. ATM’s Colony establishes this bio-filtration in days instead of weeks with real, commercial grade nitrifying bacteria.

Colony Marine contains live Nitrococcus and Nitrosococcus bacteria, which are specific for the marine environment.

The bacteria in ATM Colony are living organisms that require certain water quality conditions before use. Please follow the instructions before use.

Use:

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

Colony Marine 32 oz treats 378 litres (84 UK Gal)

Instructions:

Maintain average water temperatures of 23-30°C (74-86°F). For best results, maintain a pH between 7.2–8.0. Always maintain a minimum 90 ppm Total Alkalinity. Systems requiring a pH level below 7.2 should be slowly adjusted after ageing/cycling the system at 7.2–8.0 pH. Shake bottle vigorously to mix bacteria. For average water conditions add 118 ml (4 oz) of ATM Colony Freshwater per 95 L (25 gal) of dechlorinated aquarium water (tap water recommended). Dose entire system volume once. Do not overcrowd tank. Prevent ammonia and nitrite spikes by feeding fish lightly when applying Colony. Monitor ammonia and nitrite levels and slightly increase feeding rate after 4 consecutive days of at, or near, 0 ppm ammonia and nitrite concentrations. Gradually increase to normal feeding levels.

NOTE: Turn off or unplug UV sterilizers, protein skimmers, and ozone generators prior to and 4-5 days after each introduction of ATM Colony Freshwater. Keep at room temperature and do not allow product to freeze or exceed 43°C (110°F). No water changes until after the fourth day when all bacteria has attached.
