AquascapeAlgaecide for Ponds, Waterfalls, and Fountains – Large-Scale Algae Control, 2.5 Gallons / 9.46 L, 96053

I have a water fountain that gets morning sun. So the algae bloom gets annoying. I use the recommended amount for my feature and the next day almost clear. Then I use a clarifier and voila, clean water for at least a week.

We use the product as directed and our outdoor pond looks crystal clear and the fish are none the worse.

Luckily a neighbor read the address and brought it to me. This is for my goldfish pond.The algaecide works well. After I get the algae under control in the spring, about 1 treatment a month keeps the pond clear. This year, I have an outbreak of long stringy algae to control,

Pond is under Cypress trees and the algae gets bad during the summer. This product works great but also recommend some type of natural bio products to keep it stable.

works well

If I could give negative stars I would. The video for this product shows a woman putting it into her Koi pond which gives the illusion it is safe for Koi. It also states in its advertising to be safe for fish and plants. This product almost killed my entire Koi pond. I spent 16 hours emptying my pond in a panic because all of my fish were gasping for air, I have a 5000 gallon Koi pond with plenty of aeration as well as a large waterfall . I spoke to numerous specialist, who all told me this product should be taken off the market as it is poison. It has misleading claims and misleading advertising. I can’t stress enough not to buy this product. In addition to killing 2 baby fish, it also killed plants in my pond.This product needs to be taken off the market!!! I cannot stress enough, not to buy this product.

Bought it because it claimed not to harm fish, I don't have fish but wanted to protect frogs living in the pond. I don't think it's strong enough to kill string algea.

Easy to apply. Killed algae within 10 minutes.Highly recommend.
