Get your aquarium off to the right start with the preventative care of API STRESS COAT, API STRESS ZYME and the complete and balanced nutrition of API TROPICAL FLAKES Fish Food. API STRESS COAT treats your tap water, and provides a safe environment for freshwater fish instantly and easily. Tap water contains chlorine, chloramines and ammonia which can cause gill and tissue damage, breathing difficulty, stress and possibly fish loss. API STRESS COAT works instantly as a water conditioner to remove chlorine and chloramines from tap water and neutralize heavy metals. You can maintain a healthy environment for fish and reduce aquarium maintenance by creating a naturally balanced aquarium with API STRESS ZYME. API STRESS ZYME contains over 300 million live bacteria per teaspoonful to consume sludge and organic debris, keeping gravel and glass clean naturally and reducing aquarium maintenance over time. Use it weekly in freshwater and saltwater aquariums to maintain a strong biological filter and a healthy, clean aquarium. With API aquarium products, it’s easy to keep a beautiful saltwater, freshwater or reef aquarium. For almost 60 years API has developed premium solutions with proven and effective results for your family and ours. API offers a range of testing kits, water conditioners, and nutritionally superior food, because we’re dedicated to making a better underwater world. They work to provide a safe, hospitable environment for fish such as tropical community fish, cichlids, goldfish and more. At API, we understand the rewards and relaxation of fishkeeping because we have a passion for fish too.

The products have turned out perfect!
The products have turned out perfect, we have several fish tanks and everything has worked normally. The products come well packaged and their quality is as expected. We liked the price and quality. We have bought several things and they have all turned out good. Furthermore, well managed, it lasts a long time.

GOOD VALUE
The value for the 3-items is excellent. Only issue was that my stupid fish didn’t like the API Flake Food for whatever reason. These flakes did appear to be a bit harder than another brand that I am using. I gave the food to my brother whose goldfish was happy eating it. The other 2-bottles are items I use regularly to keep my aquarium and fish in good condition and I recommend them.

API brand works well for me.
I have used this brand of aquarium products for some time and have no complaints. This set is affordable and has large full size product bottles and ALSO comes with a can of fish food as a bonus. Whatâs not to like. Recommend.
