API Pond Algaefix Algae Control Solution
API Pond Algaefix is a powerful water treatment that helps keep algae growth under control for your underwater sidekicks. It's specially designed for areas where the water is contained without any outflow like synthetically lined ponds, water gardens and fountains. This fast-acting algicide is effective for many types of algae including green or green water algae, string or hair algae and blanketweed in ornamental ponds. So, help keep your water clean and clear for your favorite finned friends with API's solutions.
Key Benefits- Effectively controls green water algae, string or hair algae and blanketweed in ornamental ponds.
- Helps keep ponds, water gardens and ponds clean and clear.
- Algaecide controls existing algae and helps resolve additional algae blooms.
- This algae solution is safe for live plants and pond fish.
- Do not use with freshwater crustaceans, including shrimp, crabs and lobsters.
For synthetically lined pond and fountain use only, where all water is contained without any outflow. Before using, make certain that the pond has vigorous aeration, i.e. a fountain or aeration device to avoid fish loss due to low oxygen levels. When algae is controlled and removed by the filter or settles to the bottom of the pond, the oxygen level may drop to harmful levels if adequate aeration is not provided. In warm weather, pond water carries much less oxygen. Therefore, when using during warm weather and high water temperatures, vigorous, 24 hour aeration is required for the duration of the treatment. Do not shut off pond pumps and aeration devices at night. Caution: Do not use with freshwater crustaceans, including: shrimp, crabs, and lobsters.
HAZARDS TO HUMANS & ANIMALS: Harmful if swallowed or absorbed through the skin. Avoid contact with skin, eyes or clothing. Wash thoroughly with soap and water after handling.
Special Note
1-gallon bottle treats up to 38400 gallons.

Aquarium TypePond
To ensure accurate dosing, determine pond volume before use. Add 1 teaspoon for each 50 US gallons of pond/fountain water or 1/4 cup for each 600 gallons of pond or fountain water. Thoroughly mix into pond water by adding near the pump outflow, waterfall, or aeration device. It can be mixed in a bucket of pond/fountain water and dispersed evenly around the pond. Repeat dose every 3 days until algae is controlled. Be prepared to siphon out dead filamentous algae. Once algae growth is under control, add one dose per week. Weekly treatments will control algal growth and reduce pond maintenance.
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.

Koi Pond friendly
By George on Sep 22, 2019
Following the directions...it does the job! Not a quick fix, but gradually diminishes the amount of algae present leaving the pond crystal clear and sparkling. There is still enough algae present to keep the plecostomus thriving.

Works great in our small fish pond
By webomi on Jul 24, 2019
Have used this for 5 years on in our 10' x 12' shallow fish pond but this time found it from Chewy's at cheaper price and faster free shipping. Keeps rocks & water clean, non toxic to fish and water lilies. I also add a mini-bale of Barley Straw which helps to keep the water clean in our Southwest climate.

Great to use in fountain
By CHELLE3 on Jul 7, 2019
I have used this for many years in my garden fountains. It helps keep algae from growing. Even with running water algae blooms happen in the summer with these hotter days. I do change water, algae showing or not every other day to 3 days just to keep water fresh. Doesn't hurt any of the water plants, or birds that frequent the fountains.

really helps
By marty on May 17, 2019
I have a 1000 gallon pond, three koi fish frogs and plants. Had some bad algae on the rocks by our falls, more like a slim that completely covered the rocks. After several uses, this really helped. Got rid of the algae to where it is manageable. Did not interfere with my aquatic friends! Here’s the magical thing with this product....follow the directions. Would definitely recommend

Product works
By Jake on Aug 14, 2019
Product works but has to be used on a regular basis to keep algae under control. Chewy price is much better than pet store

Great stuff
By roadrunner633 on Apr 16, 2019
Could not believe I received the product day after I ordered. String moss was really bad this year in my pond. Three doses of this worked great. Still, have a little on the waterfall, but the pond has cleared up nicely.

Algae no more
By Maria on Apr 28, 2019
We had a ton of algae on our very large koi ponds. This product is by far the best we have ever used. Finally found something that works. Highly recommend.

Quick and easy shipping and purchase
By Jachump on Apr 7, 2019
I saved with Chewy on this 2.5 gallon Algaefix. I was disappointed in trying to purchase some Gentle Giant Dog food however as it is not readily available on the web site.
