Testing the Waters

In order for fish to thrive, water must be similar to that which could be found in their natural environment. Poor water quality can cause fish stress, illness and even loss. Most common water quality parameters are Ammonia, Nitrite, Nitrate, and pH. All may vary over time and all are invisible to the eye which is why it is important to test weekly. Testing aquarium water weekly will aid in keeping your most important water parameters within the proper range for your aquarium. Choose from a wide range of API testing options, such as our popular FRESHWATER MASTER TEST KIT or 5-IN-1 TEST STRIPS, for accurate water evaluation. Regular testing will help you easily determine your aquarium conditions.

Product Description

Want the secret to a healthy saltwater aquarium? The API SALTWATER MASTER TEST KIT accurately measures four saltwater parameters that are key to keeping your aquarium healthy - ammonia, pH, nitrate, and nitrite. It includes six bottles of liquid test reagent, four glass test tubes with snap-tight caps, a holding tray and a step-by-step instruction booklet with information on how to correct unsafe water conditions. With API MARINE FLAKES Fish Food you can feed your Clownfish, Wrasses, Damsels, Tangs and other marine fish a protein-rich diet scientifically formulated to promote healthy growth and clean, clear water. Overfeeding, low palatability and low quality lead to unconsumed or poorly digested food which causes waste and raises ammonia levels. High levels of ammonia are toxic to fish and can cause gill damage, stress, illness and even fish loss. The increased digestibility of API MARINE FLAKES produce up to 30% less ammonia than leading competitors and contain high-quality ingredients, such as spirulina algae and Omega-3 fatty acids to aid in overall healthy fish growth. The more nutrients your fish digests, the less waste and ammonia are released, leaving clean, clear water. 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.

1.0 out of 5 stars Missing PH Test In Kit!!!
Reviewed in the United States on March 2, 2019
The product arrived on time but once I opened the package I noticed that API did not include a High Range PH Test. This was very inconvenient as this is a critical test for my system but I see it as too much of a hassle to send back the product so I will bite the bullet and just purchase an overpriced one from the local shops an hour away. API is normally pretty good but they really let me down this round.
