Review: Tsunami DQ (great pond treatment) - I absolutely love this product. It is fairly safe for humans and pets. I just try to avoid accessing the water with animals for a week. That’s probably overkill, but I’d rather be safe than sorry. I have a 1 acre pond and I use it to keep the algae and weeds down. I treat my pond probably three times during the summer summertime sometimes four and then I use the pond eye to keep the allergy from continuing to bloom. I also use this product around my house where I don’t want grass growing or to keep weeds down and along the trail and out to my cabana great product the cost is reasonable and it’s very easy to use. I use a third of a jug with 25 gallons of water and spray my entire pond with it and I use it on the cat tails and all the weeds on the edge of the pond and it kills all of them. We used it in our rock area in the front of the house to keep the grass from growing, which is where we have our son shares. This product makes our pond extremely clear even though it is not spring fed. If you have a pond and want to keep the edge weed free and the weed growth in the water to a minimum so you can fish it, use this product. Follow the instructions to ensure you don’t kill your fish off. Have yet to kill any using it on my property. Kills grass and keeps it gone for a couple of months.
Review: IT WORKS!! - After several months of being unable to maintain our irrigation pond, a heavy growth of algae appeared across the entire surface area. Approximately 1/8th acre pond. After trying a few products we purchased Tsunami DQ Herbicide sprayed it on the algae and within 48 hours, maybe less, it was dead and had stopped reproducing itself. We were able to then remove it without reoccurrence. Tsunami was a perfect answer to our issue. Our pond is sparkling again.

### ⭐⭐⭐⭐⭐ Excellent Rapid Results
*by M***N on July 30, 2025*

We live on a 2,000 acre lake in North Central Florida. Our property has a 600 ft long, 40 ft wide private canal that leads into the lake. During the first part of this year, we experienced a drought that caused the lake level to drop with evaporation. This was the lowest we have seen the water. The low level of the water in the canal spurred crazy growth of weeds its entire length. It was mess that we were concerned as to whether we were going to have to hire a crew to manually remove these massive aquatic weeds of all types in this area. In early June, our rainy season kicked in and within a month, the lake was close to normal level and we had a completely unnavigible canal, that was choked with weeds. No way we were getting our boats out. A few years ago, we had a similar, but not as extreme problem. We tried several herbicides and weed killers that were safe for fish and wildlife and never got anything to kill the weeds back enough to remove them easily. We ended up having to hire a $7,500 crew to manually remove them. This year, we made it a quest to find something that would truly kill off all types of weeds in our canal in a rapid manner. After spending literally hours, reading literature, speaking with our few neighbors, reading reviews to see what's out there REALLY does, and viewing countless videos, we settled on a product that we have never used before, nor had we heard of called TSUNAMI DQ. We mixed as directed and applied it to the entire surface of our canal as well as the weeds themselves with 2 powered Backpack Sprayers. The results were astonishing! Within 24 hours of application, Lilly Pads, Maidencane and other weeds were already brown on exposed parts. Within 5 days, 80% of the weeds, even the tough ones, were brown and dead. Today, we are putting one last coat on the entire canal, wait a week, then drop muck tablets all over the bottom because it's definitely going to need them. This is, by far, the most effective product of its type we have ever used. I don't say this lightly. We have tried just about everything over the years and nothing else that we have tried compares. HIGHLY RECOMMEND THIS PRODUCT ☆☆☆☆☆ 5 Stars!!!
