Review on 🐠 Fritz Aquatics FritzZyme 7 Nitrifying Bacteria for Freshwater Aquariums - 32oz by Nicole Fisher

Follow the instructions and watch your fish enjoy their home. I've used this to get a new tank going and it definitely helps create/grow those beneficial bacteria. Knowing that, I'll always have a bottle handy. Make sure you check the expiry date and I wouldn't recommend using 6 months if that's the case. After opening. Shake well before each dose in the aquarium. You won't regret your purchase and your fish will thank you. if they could talk, of course.
