- Quickly establishes beneficial bacteria in new aquariums and speeds up the aquarium cycling process
- Helps prevent fish loss
- Fortifies beneficial bacteria in established aquariums
Fritz Zyme 7 is live beneficial bacteria in a bottle. Adding it to your aquarium will help increase the beneficial bacteria count. In a new aquarium, this helps to establish the beneficial bacteria that breaks down fish waste, which means you can add fish to your new aquarium sooner.
In an established aquarium, FritzZyme 7 helps if you are adding additional fish or increasing the amount of food that you are feeding. It can help rebuild the beneficial bacteria population after a power outage, after you have done a deep cleaning (where beneficial bacteria can be disrupted during the cleaning process), and after you have changed filter cartridges or filters. It can also be used after you have changed water and finished medicating an aquarium to help reestablish beneficial bacteria.
Customer Reviews
Absolutely, love this product and would never use a different brand.
I use this along with Dr Timms ammonium chloride to cycle all my new tanks!
Worked wonderfully
Works great
Definitely helps to cycle an aquarium faster and to up the BB after big changes! I love Fritz products!
And it’s pink with no smell, I keep my unopened bottles in the fridge to prolong life.
My first experiences with Fritzyme have been positive. Seems to really help establish helpful bacteria more quickly than other bottled formulas
I LOVE fritzyme 7. I use it in every new tank setup even with a seeded filter as a CYA measure. Shipped quickly and without any issues. Thanks Coop!
Perfect exactly item i was recommended to get
Nitrites started showing up only 4 days after adding, I had my doubts about it working, but im very very impressed
This worked well to cycle my tank. I haven't used any other brands, so I have nothing to compare to (Although I tried cycling with no added bacteria, I don't think it would have ever happened, so thankfully Fritz Zyme 7 was there to help). Most people online felt that this was a more reliable brand than many others. And I trust Aquarium co-op to handle it well. I bought a large bottle and saved some of it to use later as needed long before the expiration date. But it didn't seem to work later and it no longer had a smell. My second bottle the smell seems to slowly be diminishing even after a week of being open. I continue to buy them, but only the small bottles and once it is open I use it all within a month or so, and just keep an unopened small bottle on hand as needed. I wish the bottle would have a warning on it, telling me how long it is good for after opening.
