About This Product

Stop algae growth in its tracks! TotalPond Algaecide restores the health of your pond or water feature by preventing green water, eliminating existing algae, and resolving additional algae blooms. It effectively controls many types of green or green water algae, string or hair algae, and blanketweed in ponds that contain live plants. One 16 oz. bottle treats up to 4,730 gallons of water. Add 1 tsp (5mL) for every 50 gallons of pond or fountain water. Once algae growth is under control, add one dose every 5 days. Weekly doses of Algaecide will control growth and reduce pond or fountain maintenance. During warm summer months, adequate aeration is required. So, pumps and aeration devices should be kept on at night when using this product. For ornamental water feature use only, where all water is contained without any outflow. TotalPond Algaecide is EPA-registered and can be used in ponds with fish and plants.

    How fast does it take to clear the water

    Answer This Question

    hello Susan, thank you for your inquiry. It would depend on how bad the algae is. We always suggest testing the water before using any water treatment to make sure you are treating the correct issue. If the algae isn't cleared after the first application, you can reapply every 5 days until it is. Then you would use it once a week for maintenance. Make sure to use the correct dose and use extra aeration as Algaecide will deplete the oxygen in the water. When used as directed, it should work fine. There really isn't a time frame since we don't know how bad your situation is. We hope this helps! Your TotalPond Water Gardening Specialist, Cindy

                Does this product cause foaming and bubbles?
                ByDec 2, 2025

                Answer This Question

                Hello John, thank you for your inquiry. Yes, sometimes algaecide can cause foaming or bubbles. when mixing algaecide with water and organic matter they can trap air and create bubbles. Also, when algae decompose, they release proteins and other organic compounds that can act like natural foaming agents. Aerator, fountains, and the combination of surfactants and organic matter can make foam more noticeable. We hope this helps! Your TotalPond Water Gardening Specialist, Cindy

                    This will kill your fish
                    On the 16oz bottle I bought it says "safe for fish" but my fish got very sick when I used this product. If you look on the Total Pond website it says " Wait at least 7-10 days before adding fish to the water". They don't even know what they are talking about, which is correct?. Are the instructions on the bottle correct or is their website correct? DO NOT PUT THIS IN A POND WITH LIVE FISH, IT WILL KILL YOUR FISH.

                      I have a 3 foot x 5 foot pond, with no fish. The water was murky green and sludgy. I could not see the bottom. I added 1/4th the bottle on 5/9/19 that evening. I checked the pond on 5/11/19 at 10 am and the pond was crystal clear. I am so pleased.

                        Our small fountain is in direct sunlight and we have fits with the algae. Both the look (green water) and the way it clogs the small pump. One capful of this product changed everything. Love it!

                        I bought this Total Pond Algaecide after several attempts to get rid of the algae in my fountain. Salt didn't work, other products didn't work. Several times I even drained the fountain and scrubbed the pot clean, but the algae came back right away. When it got to the point that the frog spitter looked like he was barfing gook instead of spitting water and my neighbors wanted to call paramedics or an exorsist to save the frog, I decided to give this product a try. It did not work instantly the 1st time that I used it, but within a couple of days the water was clear, now every time the water starts to look a little green I add a little of this Algaecide it the water clears right up.

                        have been using in a small fountain for several years... seems to do its job, but given the AZ evaporation rate and that the fountain has to be refilled at least every day, the algaecide requires frequent applications, using maybe a bottle every 6 months?
