API QUICK START Freshwater and Saltwater Aquarium Nitrifying Bacteria 8-Ounce Bottle

I’ve been using the API Freshwater and Saltwater Aquarium Nitrifying Bacteria for a while now, and it’s been a great addition to my tank care routine! The 8-ounce bottle goes a long way, and it really helps maintain a healthy environment by supporting the growth of beneficial bacteria. My fish tank’s water quality has improved, and I feel more confident in keeping my fish healthy. Easy to use and effective—highly recommend it for any aquarium owner! 🐟💧

I have used this for years and years in my aquariums and my aquatic turtle tanks. I use the one for ponds because it’s more concentrated and a better value than using the one for regular aquarium size tanks, Especially if you have many tanks. My fish and turtles are all very healthy. It helps remove chlorine neutralizes chloramines, detoxifies, heavy metals and just generally makes the tapwater safe for aquatic pets and you can even use it for your house. Plants when you’re watering them.All in all, I love API products And I will continue using their water treatment As long as I have aquatic pets

Great for water clarity and fish health. Large size is value for your money for larger tanks. A must have for new set ups and water changes.

I tried every other method to lower the nitrites in the tank and could tell my betta was getting unhealthier and more stressed by the day. Less than 24 hours after using this, he was active again. 48 hours later, he was acting completely normal and eating for the first time in a week. Couldn’t recommend it enough.

Worked great cycled my tank fast fish doing great and ammonia,nitrites, and nitrate gone.

Very high quality product that I trust with my fish. It takes DAYS off the time it takes to set up your tank.It's easy to dose so it's safe, and great for the health of your fish. I don't put fish into a new tank until I've added Quick-Start!

Arrived as promised, works as it should. Good value

I wouldn’t go with any other brand
