Product Overview
I recently used Crystal Blue Tsunami DQ Aquatic Herbicide to take care of some pesky weeds in my pond. I was initially hesitant to try this product, as I ve had bad experiences with other herbicides in the past. But after much research and deliberation, I decided to give it a shot.
The product comes in a 32 fluid ounces bottle and is made up of 37.3 diquat dibromide, which is an effective herbicide for both surface and submerged weeds that are copper resistant. Its active ingredient is also proven to be successful for hard to kill weeds like duckweed, which was one of the primary problems I had with my pond.
I started off by applying 2 quarts of Tsunami DQ per surface acre depending on the infestation type of weed for aquatics, and then followed up with Plex Mate to enhance its effects when treating floating marginal weeds. After just a few weeks of using this product, I could already see a huge difference in the amount of vegetation growth in my pond.

I was really impressed with Crystal Blue Tsunami DQ Aquatic Herbicide. It was very easy to use all it took was mixing the product with water according to the instructions and then applying it directly onto the affected areas and it worked wonders! Even better, it didn t cause any harm or damage to any of the surrounding wildlife or foliage, which is something I always worry about when using herbicides.
Overall, Crystal Blue Tsunami DQ Aquatic Herbicide is an excellent choice if you need a reliable solution for controlling unwanted vegetation growth in your pond or lake. It s effective yet gentle enough that it won t cause any harm to your local wildlife or plant life. Plus, at only 2 pounds and 5 x 2 x 11 inches in size, it s easy enough for anyone to handle and apply safely.
If you re looking for a reliable herbicide that won t put your local ecosystem at risk while still getting rid of those pesky aquatic plants once and for all, then look no further than Crystal Blue Tsunami DQ Aquatic Herbicide you won t regret it!
