Fritz FritzZyme 7 Freshwater

Description

  • The Original Live Nitrifying Bacteria
  • No Need for Refrigeration and One Year Shelf Life
  • Rapidly Eliminates Toxic Ammonia and Nitrite
  • FritzZyme® 7 is Good for Fresh and Brackish Systems
  • Great for Use After Maintenance

FritzZyme® 7 contains live freshwater-specific strains of live nitrifying bacteria proven to reduce fish loss due to toxic levels of ammonia and nitrite. Nitrifying bacteria can take weeks to naturally establish colonies in new aquariums while ammonia and nitrite can reach lethal levels in only a few days. FritzZyme® 7 provides the proper balance of bacteria proven to rapidly seed biofilters, greatly reducing the natural cycle time allowing for safe, faster addition of livestock.

FritzZyme® 7 may be added to new tanks or established systems any time the biofilter needs fortification including: after water changes, aggressive cleaning, adding new livestock, medicating or changing filter media.

Why add nitrifying bacteria?

Nitrifying bacteria can take weeks to naturally establish colonies in new aquariums while ammonia and nitrite can reach lethal levels in only a few days. FritzZyme® Live Nitrifying Bacteria provides the species of bacteria proven by professional zoos, aquariums, universities, and aquaculture facilities to rapidly seed biofilters. FritzZyme® quickly removes toxic ammonia and nitrite in existing systems and greatly reduces cycle time allowing for safe, immediate addition of livestock in new systems. FritzZyme* Nitrifying bacteria may also be added any time the bio-filter needs fortification including after water changes, aggressive cleaning, adding new livestock, medicating, or changing filter media.

Live, Viable Product

Unlike some heterotrophic bacteria, which can survive in a long-term spore state, only true nitrifying bacteria can cycle an aquarium. True nitrifying bacteria are fragile and temperature-sensitive, which is difficult to produce and package. FritzZyme® 7 is buffered for long-term stability without the need for refrigeration.

Years of Proven Success

Fritz Aquatics has been continuously producing the highest quality, viable, nitrifying bacteria for over 30 years and was the first company to commercially produce nitrifying bacteria for the aquarium industry. Fritz Aquatics has remained a leader in the industry with continuous research, production, and development. There are very few producers of true live nitrifying bacteria, none of which can match the experience and success of FritzZyme®.

    Testimonials

    Reviews from pet professionals across Europe, trusted voices from the shelves.

    • We’ve been working with Xtra for over a year now, and the experience has been nothing short of excellent. From the start, their team took the time to understand our store's profile and helped us build the perfect product assortment. Orders arrive quickly, the packaging is retail-ready, and our customers love the quality. It’s rare to find a supplier that combines efficiency with such a personal touch.

      5/5 Sophie, Owner of The Pet Corner (NL)
    • Xtra feels less like a supplier and more like a partner. We appreciate how easy it is to reorder, and how well the product photos and descriptions are made for online use, a huge help for our webstore. Their advice on bestsellers and seasonal trends has helped us improve our sell-through rate significantly. Highly recommended for any pet retailer looking for quality and consistency.

      5/5 Marco, E-commerce Manager at Paws & Play (DE)
    • As a grooming salon, we don’t carry a massive inventory, so having a reliable supplier like Xtra is a game changer. We love that we can order small volumes and still get fast delivery and great service. The dog accessories, especially the toys and rucksacks, are a big hit with our clients. Plus, their B2B portal is super intuitive and saves us time every week.
