Overview

Nitr8 provides a concentrated consortium of live nitrifying bacteria that rapidly establishes and fortifies biological filtration in marine aquariums. It helps convert toxic ammonia (NH₃/NH₄⁺) to nitrite (NO₂⁻) and then to nitrate (NO₃⁻), supporting stable cycling, resilient biofilters, and healthier livestock.

Key Features

• High-density nitrifiers to seed new tanks and boost mature systems

• Speeds cycling and helps recover after disruptions (medications, deep cleanings, power outages)

• Reef-safe for fish, corals, and invertebrates when used as directed

• Clean, fast-dispersing liquid with no dyes or perfumes

• Pairs well with Captiv8 carbon sources and trace regimens

Directions & Dosing

General Use:

• Shake well to resuspend bacteria.

• Turn off UV/ozone and remove filter socks for 12–24 hours after dosing to maximize colonization. Resume normal operation afterward.

• Dose into a high-flow area or directly into the bio-media chamber.

New Tank / Post-Reset (Day 1):

• 5 mL per 25 gal (95 L).

• Add an ammonia source (light fishless feed or ghost-feeding). Keep temperature and salinity stable.

Follow-Up (Days 2–7):

• 2 mL per 25 gal (95 L) daily until ammonia and nitrite consistently read 0 ppm.

Biofilter Boost (After Media Changes, Power Outage, or Medications):

• 5 mL per 50 gal (190 L) once daily for 3 days.

Ongoing Maintenance (Optional):

• 1 mL per 50 gal (190 L) weekly, or after large water changes, to sustain robust populations.

Notes:

• Avoid overdosing ammonia binders during cycling—they can mask readings and slow progress.

• Test ammonia and nitrite regularly and adjust feeding/bioload accordingly.

Compatibility

• Safe with reef fishes, corals, and inverts.

• Compatible with protein skimmers, carbon dosing, and trace programs; just pause UV/ozone for a day after dosing.

• Works with most rock, sand, and ceramic biomedia.

Ingredients

• Live, non-pathogenic Nitrosomonas/Nitrosospira (ammonia oxidizers) and Nitrospira/Nitrobacter (nitrite oxidizers) in purified water with stabilizers.

Storage & Handling

• Store cool and dark; do not freeze or overheat.

• Keep tightly capped.

• For maximum viability, refrigeration is optional but beneficial after opening.

• Keep out of reach of children and pets.
