API Quick Start Nitrifying Bacteria for Freshwater and Saltwater Aquariums, 30 ml Bottle

Superb product. API is one of my resources for many of my aquarium essentials. Never had any problem with any of there items. Great value for money, with many products giving you size options for what you need. All products from medicated to water parameters and plant care. These products are made with an ease of understanding for what that purpose is and will help you on your fish keeping journey.

Working well. My go to when starting a new tank.

Great product and excellent customer service. My first bottle arrived empty, but the seller sorted it out straight away and sent a replacement very quickly with no hassle. Really appreciate how fast the problem was resolved. Very happy with the purchase and would definitely buy from this seller again.

I brought this to do a fishless cycle. I didnt want to add fish as I didnt want them to die due to the tank not being cycled. After nearly a week I didnt notice any change to the water and my readings didnt change. The bottle does say that you CAN add fish immediately BUT it doesnt say add the fish because you need their amonia for the quick start to actually work! The bottle doesnt include any amonia at all. So I brought some liquid amonia and another quick start and tried again. After waiting and testing for weeks for the cycle to start it just didnt. It completely stalled. After a large water change it seemed to fix the issue and now my cycle has finished and I have my first 2 fish. This very long and costly wait would all of been solved if they had simply said you need to add a source of amonia for the quick start to work. I wouldnt buy this again. Next time I'll add liquid amonia and let nature take its course.

Got this as a cheaper alternative to the more expensive axolotyl versions and it has been great. Like people have said it is quite small but it is also perfect as you only add a couple of drops each time.

Great product

It is good stuff but wait 4 weeks before putting any fish in your tank. Plants growing very strong.

Do the job as required

Its good to rapidly reduce ammonia

I was aware of the amount because I did read the description but it was still a little disappointing, haha. That’s just me. Good product though.

Highly effective Improves water quality by maintaining bacterial colonies Easy to use... Rather than other products. Must to stepup a new tank.. also it is good to add once in month so replenish the bacterial colonies

Helped us speed up aquarium set up and cycle time. Little to no odour. Very pleased with how it worked to jumpstart a bacterial culture. Highly Recommend!

Good
