FritzZyme 7 Freshwater Nitrifying Bacteria

Introduction

FritzZyme 7 is a concentrated liquid formula containing live freshwater nitrifying bacteria, designed to accelerate the cycling process and establish a stable biological filter. Ideal for new tank setups, restarts, or boosting filtration in established aquariums, it quickly converts harmful ammonia and nitrites into less toxic nitrates, creating a healthier environment for fish, plants, and invertebrates.

Features

• Live Nitrifying Bacteria: Supplies a potent blend of beneficial bacteria to jumpstart the nitrogen cycle.

• Faster Aquarium Cycling: Reduces the time needed to make tanks safe for fish.

• Ammonia & Nitrite Conversion: Converts toxic compounds into safer nitrates.

• Versatile Application: Suitable for new setups, after cleanings, or during filtration upgrades.

• Safe for All Freshwater Life: Compatible with fish, plants, and invertebrates without risk.

Directions & Dosage

• Preparation: Remove all chlorine/chloramines before dosing.

• Cycling: Add an ammonia source (e.g., livestock or Fritz Fishless Fuel) for bacteria to feed on.

• Equipment: Maintain aeration/flow; turn off skimmers and UV sterilizers for 5 days after dosing.

• Application: Safe to use with livestock present and with other products/medications.

• Storage: Keep in a cool, dark place. Do not freeze or overheat.

• Note: Odor and color variations are normal; a sulfur smell does not mean the bacteria are inactive.
