What does API ACCU-CLEAR do?

API ACCU-CLEAR clears green or cloudy water in freshwater aquariums by clumping small particles together into larger pieces, so they can settle to the bottom of your aquarium to be siphoned out, or easily removed by the filter.

Is API ACCU-CLEAR safe with fish and plants?

Yes, API ACCU-CLEAR is a safe product for both fish and plants.

Why can’t API ACCU-CLEAR be used in marine aquariums?

In water with a high mineral content, such as the water found in marine (or saltwater) aquariums, API ACCU-CLEAR will not clear cloudiness and could even make it worse. However, API ACCU-CLEAR will not cause any harm to fish or marine plants.

Can API ACCU-CLEAR be used if I have added salt to the water in my freshwater aquarium as part of a supportive treatment for fish?

Yes. A low level of salt in the water, as is typically the case with freshwater aquariums, is not a problem with API ACCU-CLEAR. However, API ACCU-CLEAR does not act as a healing treatment for fish like aquarium salt. Its primary purpose is for aquarium cleanliness and clarity.

Will API ACCU- CLEAR clear the cloudiness caused by bacterial blooms?

API ACCU-CLEAR will help to clear the cloudiness caused by bacterial blooms, but does not address the underlying cause. As a result, the cloudiness will come back quickly unless the main cause of bacterial blooms is treated.

Can I repeat the dose of API ACCU-CLEAR if the cloudiness persists?

API ACCU-CLEAR can be dosed again after 24 hours. However, further doses should not be added after this, as repeated doses will actually make cloudiness worse. API ACCU-CLEAR can be dosed once a week as a routine treatment to help keep water clear, but if cloudiness persists, you may want to perform a 25% water change.

Can API POND ACCU-CLEAR be used in fish tanks?

API POND ACCU-CLEAR is specifically formulated for use in freshwater ponds. Please use API ACCU-CLEAR for best results in a fish tank.

Is API POND ACCU-CLEAR safe around pets?

API POND ACCU-CLEAR is for ornamental pond use only, but is safe for fish, pond plants, and surrounding wildlife when used as directed.

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.
