API QUICK START Freshwater and Saltwater Aquarium Nitrifying Bacteria Bottle,...

Its good to rapidly reduce ammonia

Won’t recommend this product for cycling your new tank.

Product damage and leaking

it took me weeks to start the cycle

Tried a few other types and this one works the best for my fish. They are happy and healthy, which means so are we!

Very good for the money. Works as good as a bacteria in a bottle can work!

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

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.

Great price quality first class
