FAQ

Should API ALGAEFIX and ECOFIX be used at the same time, or should sludge remover be added after all the API ALGAEFIX treatments are completed?

It is best to use API ALGAEFIX on its own until algae is under control.

How much API ALGAEFIX is needed per gallon?

To ensure accurate dosing of API ALGAEFIX, determine pond volume before use. Add 1 teaspoon for each 50 U.S. gallons of pond/fountain water, or ¼ cup for each 600 gallons. Thoroughly mix into pond water by adding near the pump outflow, waterfall, or aeration device. API POND ALGAEFIX may be mixed in a bucket of the pond/fountain water and dispersed evenly around the pond. Repeat dose every 3 days until algae is controlled. Be prepared to siphon out dead algae. Once algae growth has subsided, add one dose of API POND ALGAEFIX per week, as weekly treatments will control algal growth and reduce pond maintenance.

API ALGAEFIX is designed for use in synthetic-lined ponds and fountains only.

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.

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.

    Product works

    By Lewrose2 on Sep 3, 2016

    Not much to say. I followed the directions and all of the algae was gone in about 5 days. All of the marine life still alive. This is a cold water Long Islan Sound tank. The grand children collect snails, hermit crabs, shrimp, minnows and any sea life they can find and throw them in. I usually get a few severe algae blooms every summer. Happy I found something that takes care of the problem
