About this item

Product details

API® Quick Start allows for the instant addition of fish, as it immediately starts the natural aquarium cycle with beneficial bacteria, which converts toxic ammonia into nitrite, then into harmless nitrate to help prevent fish loss in your tank. Best for use when starting a new aquarium, after water changes and filter changes, and when adding new fish to an existing aquarium. API Quick Start may be used in both fresh and saltwater aquariums.

Makes cleaning my tank so much easier

[This review was collected as part of a promotion.] Cycling the tank has never been easier. The fish are happy, the water is clear and setup was smooth. The directions on the bottle are easy to follow. This is an easy to use product for beginner fish owners.

Nice

[This review was collected as part of a promotion.] Worked really well. My fish seem to be really happy and the adjustment was very easy. Easy to use and makes maintenance almost non existent in the beginning.

Fishes quick start

[This review was collected as part of a promotion.] Quick start speaks for itself. It gives you the short to quick ability to add fishes to an aquarium without them carrying any bacterias from different aquariums. It's shows quick and easy transfers no matter the water type.
