Aquashade Blue Pond Dye - 1 Gallon EPA-Approved Sunlight Blocker for Algae - Weed Suppression - Safe for Fish, Livestock and Swimming - Eco-Friendly Liquid Treatment for Water

I have been using this product for almost 20 years..works great in a 2 acre pond to control unwanted weeds and algae. It also turns the water a beautiful shade of blue. Have tried other pond UV blockers and this by far the best. Highly recommended

Pretty awesome product, just wish it wasn't so costly. Very easy use.

I have used a lot of pond dye through the years. This stuff does more than just color water . I does what it claims. Controls algae and unwanted Weeds .

Worked great in our pond

I have a very small pond, 3'x5'x 3' deep. Because it is so small, even with the waterfall going all the time it heats up and gets algae growth fairly quickly. I use an algaecide, but thought the Aquashade might help. There is no guideline for anything as small as my pond, so I took a teaspoon, dipped it in the liquid, let the majority drip off and just used what stuck to the spoon and swirled it in the water. It turned the water a lovely blue green and I wouldn't want to use any more than that. We'll see if it helps deter the algae growth.At this rate, the bottle I purchased will last me 3 lifetimes!

Why did you pick this product vs others?:This is the best product for ponds

Works great!!!

Great for my pond. And I didn’t have to go out and search store to store to find it and it was delivered right to my door
