Great product I buy their stuff all the time
Iโve been keeping freshwater fish tanks for five years now I do use API a lot more than some other companies because for my needs it does a great job. You can rely on a PI to deliver, and if there is any problem, you can contact the company they have pretty good Customer service. They too are enthusiasts in the hobby and also lifestyle, but they also understand that sometimes things go wrong. In my opinion, API is a great company. I would love to do some YouTube videos and maybe they would sponsor me.

Seems to be a quality product and not outrageous price, but does it work? Who knows? LOL!
I needed to do a MAJOR clean and overhaul of the primary water filter in my 75 gal tank. I was confident doing so would throw off the beneficial bacterias that filter the water and prevent toxic buildup of nitrates, etc. I read a number of reviews that recommended this product for when water changes were done, not just new tank setups. I can say that after thoroughly cleaning and replacing parts of the filtering system, changing water (25%), and applying this product per instructions on the bottle, my fish and plants showed zero stress and my chemical water parameters testing kit over 2 days showed perfect levels. So it must work, right?

Effective at promptly starting the nitrogen cycle
This product is effective at initiating new tanks with a minimum of 1-2 fishes before adding more. Patience is key with a reliable water test kit.

Great product!
This is such a great product for aquarium set ups, at the start up or clean up stage. I've used it to cycle my 3 gallon tank for a single betta. Very convenient to use and quality of aquarium water is clear and clean. I'm using a sponge filter with API Quick Start - I add some to my tank water according to the instructions, every time I clean the aquarium. It's working well for me to date.
