Review: Effective Algaecide - We have a 2 acre pond that developed a serious filamentous algae problem this spring due to all of the fertilizer run off from surround fields. About 40% of our pond became covered with thick mats of algae when the temps reached 85 - 90. I have a 15 gallon sprayer that will spray out about 30 feet and was told to mix at the rate of 1 gal Cutrine to 9 gal of water. I also mixed in 22 oz of Cygnet Plus as a surfactant and sprayed along the shoreline and used a a jon boat to spray the rest of the pond out in the center. The first time I sprayed the algae was dead within 24 hrs, however I've needed to reapply whenever I see regrowth. But the product works well. While it didn't bother our turtles and fish I was told that Koi and Trout are very sensitive to this product. However the packaging they ship the jug in is really crappy! Just an over sized flimsy box with no bubble wrap or paper and twice the 2.5 gallon jug has arrived with the box damaged & the seal on the jug broken and the chemical leaking thru the box. Not good!
Review: Slow to work but works great - I’m updating the review in this because the product took a little longer to work but our pond looks amazing after two week and only half the container

### ⭐⭐⭐⭐⭐ GOOD STUFF ! Blocks Sunlight, inhibits bottom and other algae growth. Good Color.
*by C***X on August 15, 2022*

GOOD STUFF ! Blocks Sunlight, inhibits bottom and other algae growth. Good Color. Not as Disney Land/World green as some dyes can be. This doesn't quite look natural, but best I have found. Natural would not dye water at all. We are in Houston, and heavy bright long sunny hot days demand using a dye in our One Acre lake. We are able to get about two treatments from one container. Without this dye our water would be crystal clear and the pond would turn over or blossom with algae growth. This prevents it.
