About API Pond Algaefix
Why Use API POND ALGAEFIX Algae Control?
Algae growth can appear as “green water” blooms, “pea-green soup”, filamentous algae on plants, or as floating mats known as blanket weed. Algae grows when there are excess nutrients in the water—usually in spring prior to plant growth or during summer in direct sun. API POND ALGAEFIX Algae Control works quickly to control algae growth and keep ponds, water gardens and fountains clean and clear.
Controls Most Types of Algae
Before Using
Make sure your pond has vigorous aeration 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, oxygen may drop to harmful levels without adequate aeration. Pond water also carries much less oxygen in warm weather.
Algae Types
API POND ALGAEFIX helps control three main types of algae:
1. Green Water Algae (Chlorella)
2. String or Hair Algae (Cladophora)
3. Blanket Weed (Oedogonium)
How to Use API POND ALGAEFIX Algae Control
Treating your pond to control algae is simple. For best results, be sure to read and follow all label directions.
Step 1
Vigorous 24-hour aeration is required during treatment. Do not shut off pond pumps or aeration devices at night.
Step 2
Remove as much algae as you can by hand before treating your pond.
Step 3
Disperse API POND ALGAEFIX evenly around the pond and thoroughly mix it into the water. DO NOT OVERDOSE.
Step 4
As algae dies off, remove as much of the dying algae as possible.
Calculate Pond Volume Before Use
To ensure accurate dosing, determine your pond’s volume and then use the dosing chart to figure out how much API POND ALGAEFIX to use. For square and rectangular ponds: avg. length (feet) x avg. width (feet) x avg. depth (feet) = cubic feet of water. Cubic feet of water x 7.5 = volume in U.S. gallons. For round ponds: top diameter (feet) x bottom diameter (feet) x height (feet) x 0.785 x 7.5 = volume in gallons.

Works as Informed
Followed instructions to the t and product worked in 2 days.
Very Effective
I bought a house with a 3000 gal koi pond/fountain not long ago. The pond is equipped with 2 stages of filtration. The previous owner fought murky green water for years with limited success. The very large, brightly colored Koi were barely visible. I started looking for an algaecide and settled on API Algae Fix. Within a few weeks the pond was crystal clear and remains so with regular treatments. I read several comments about the danger to fish. I have several large, valuable Koi so I was very careful to follow instruction about dosing. I measured the pond carefully to get an accurate water volume including the volume in the filtration and circulating system to determine the proper dosing. My pond is also equipped with a secondary aeration system which ensures adequate O2 saturation. This product is very effective and safe for fish but the buyer should follow the directions and warnings carefully. I am very satisfied with the product.
Horrible packaging
Ordered this along with 5 litter pan deodorizer sprays. They packed them all together and I’m assuming because the algaecide was a gallon and the cat spray was small it caused the algaecide to leak along with the cat sprays. What a mess. I called and questioned why they would pack them together and she said she would ship out a replacement but packed in separate boxes. NOT. They all came together again and this one leaked. Ridiculous
Outstanding purchase
I was amazed at the purchase I made for some very expensive pond algae preventer. Algaefix is the best product I have found to prevent algae growth in our pond. We have a 10,000 gallon pond so we go thru a lot of this stuff. When I found it online at Chewy the price was not to be believed! I saved a bundle and they shipped it in a day! I will always check Chewy's prices now before I purchase anything for my pond!!!
Algaefix works!
We have a new small pond and waterfall. It developed a bit of algae since we don't have any fish in it. The Algaefix worked after 2 doses. Very happy with the product.
Algae mostly gone
After more than a week of treatment every third day the stringy algae almost Gone. There is still a little on bottom so another treatment last night. Tough algae to get rid of.
works great
I have tried a couple other treatments for my fish pond and without good results. This stuff works great. Love it
Nothing at All
It literally did nothing. I mean absolutely nothing, not even when double dosed and give more time the directions state to work. Kind of feel it made it worse.
