API QUICK START

I’ve 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.

Works great for our tanks!! Great value for the money!! Lasts a lot longer then the small bottles from the other stores!

The API QUICK START for freshwater and saltwater aquariums is a total game-changer—especially if you're setting up a new tank or adding fish to an existing one. It makes the nitrogen cycle process way less stressful, both for you and your fish. I used it when starting a new freshwater setup, and within 24 hours my tank was safe and stable. No ammonia spikes, no nitrite issues—it genuinely helps establish the biological filter FAST. It's also great to use after water changes, adding new fish, or cleaning the filter. What I love is that it’s super easy to use—just shake and pour. The bottle gives clear instructions, and the results speak for themselves. My fish were active and healthy from day one. This is one of those products you always want on hand. It helps create a healthy environment and gives peace of mind whether you're a beginner or a seasoned aquarist.

The API QUICK START works like a charm! I used it when setting up a new aquarium, and it helped cycle the tank quickly with no ammonia or nitrite spikes. Super easy to use, and safe for fish—my water stayed clear and healthy. Highly recommend for both beginners and experienced fish keepers!

It works for a quick start up but I prefer a different brand

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?

Must have for any fish tank owner! Great product and good bottle size for the price. This is my first refill - the first bottle lasted me nearly two years.

Quick shipping, exactly as on the ad! Great item! Thanks!

Its good to rapidly reduce ammonia

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
