Highly recommend
This stuff was amazing! We’ve had stubbornly pads in our pond for two years. We use this along with Airmax defense, and they are finally dying off and will be able to remove them soon. We’ll definitely use in the spring to keep others from growing.

Aquatic weed killer and algae
This is really good stuff, but definitely do not make it too strong. It will even kill grass around. The pond if made to strong a bit pricey though

A game vhanger in pond management
Although it is quite pricey, it’s well worth the money. We have used for several years and it is very fast acting and easy to administer.

Super fast results
We have a small pond (maybe 1/4 acre) and it is shallow. So we get a lot of algae due to warm temps and sun hitting the bottom. I apply this via a hand pump tank sprayer and a kayak. I’d suggest rigging it so the nozzle is just below the surface and then just paddle around for coverage. Note that before initial treatment I did skim as much surface algae as possible to help reduce how much dead algae sinks to the bottom. Be advised that it will affect other plants in the pond if you have them. We had an over grown section of cat o nine tails at one end and their growth is noticeably stunted.

Incredibly effective for duckweed. Killed all vegetation.
Absolutely blown away with how effective this product is. I used a single application as directed and it removed 100% of the duckweed in about 2 weeks. I planned a second treatment, but patience was all that was needed. Incredible product, wish I found it sooner. Also this pond is used for irrigation of the lawn and beds. I waited 5 days as per instructions before using for irrigation and had not issues with my lawn or plants. After pic shown first.

Worked in 5 days
We bought this after Sepro RTU failed. I used 1/2 the bottle and it killed the duckweed quickly. We started to notice die off in 3 days and total kill/clear water in 7.

Works great
I use this for algae in our 1 acre pond and have always been pleased with the results. As it stated it will also kill weeds, so you want to be careful what it sprays on if you have plants you don't want to be harmed. For me I have found this is nice to help take some unwanted weeds out while taking care of the algae. Over the years I have tried a lot of different products, but using pond die to handle the most part and this when/if an algae starts, it keeps things in check.
