Proven Efficacy
Low levels of ammonia and nitrite will harm fish; high levels will kill fish. QUICK START is proven to reduce exposure of fish to ammonia and nitrite. QUICK START helps prevent fish loss by avoiding dangerous spikes of ammonia when starting your aquarium. The live, nitrifying bacteria in QUICK START speed the development of the biological filter to keep fish safe.

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.

I recently bought a tank and betta fish for my niece. I use this to get the tank started and also use it for every water change. Our betta has been growing and is loves his tank. I have a 5 gallon tank so I use half of the recommended dose which is 5ml per 10 gallon tank. This will last me a while as I do a 10% water change one per week or 25-30% once a month. Since I'm using tap water I find using slightly warm water and the adding the quick start to the water before adding to the tank has helped. I usually let it sit for about 15 - 30minutes before adding the fresh water with the quick start to the tank. I highly recommend!

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

I have a 20 gallon fish tank and this is a necessity to keeping the fish healthy. This is a better value to purchase in a larger quantity than the smaller 10 ounce bottles. For the size of my tank this large bottle makes it hard to measure and pour the correct amount so I did keep a smaller bottle that I had previously to refill from this one. It has kept my fish healthy and would recommend this product for your tank.

Another excellent product from API which does the job as required. In this case it's Bacteria to add to the Filter to service the well-being of the tank water when setting up a fresh aquarium or adding new fish to an already established one.

Works great cutting Ammonia. Keeps your fish safe keeping the water clean. Great value for the money because I only used one cap full in my 75 gallon tank to receive the benefits of using this product.
