Fishkeeping is a much easier task with API, because they've taken all the guesswork out of setting up a tank and maintaining it. Their proven treatments include water conditioners and clarifiers, fish medications, pH adjusters, algaecides and quick-start solutions—all designed to keep your aquarium crystal clear and your fish happy and healthy.

Testing Is Key

Once you've started a new aquarium, the only way to keep it in perfect balance is with routine water testing. API gives you all the tools you need to create a nurturing environment for both fish and live plants. Their comprehensive Master Test Kits are tailored to freshwater, saltwater or reef environments, and individual tests for things like pH, ammonia or nitrites leave nothing up to chance.

Clearing the Water

Clearing the Water

API offers reliable three-step filtration for tanks of all sizes with their FILSTAR XP Canister filters and wide variety of filter media. These powerful filters constantly circulate the water, trapping organic waste and odors, removing harmful ammonia and contaminants, and helping good bacteria to thrive in the tank.

Superior Nutrition

Feeding your aquarium inhabitants, whether they're tropical fish, turtles or newts, is something that can be tricky without the right food. API developed a special diet for every type of fish—one that's highly palatable, which leads to less waste in the tank. And that means less ammonia to cloud the water. For your turtle friends, premium floating pellets and stick treats provide multiple vitamins for a stronger, healthier shell.
