Aquascape Algaecide for Ponds, Waterfalls, and Fountains – Fast-Acting Algae Control, 32 oz / 946 ml, 96024

Works very well and is not harmful to wildlife. We have a small waterfall and pond feature in our back yard and it keeps the algae from growing. A little goes a long way too.

I live in a hot humid climate. I have a small pond that is about 15 inches deep. No fish but lots of tadpoles that I don't want to harm. Pond was very green and gooey from the heat. My fountain pumps lots of water so I used this product per label instructions. Water started to clear up nicely. So I drained and cleaned the pond and added all new clear water. I've been using this product as directed on the bottle and the water has remained clean and clear. The cost is reasonable. I will definitely purchase this product again.

This is a good product to control algae in small ponds when used as directed. Safe for fish and aquatic plants.

Our fish pond began having algae growth after a tree was removed so we added this to the pond and began seeing the algae separate from the rocks within a few days. We’ve been adding it to the pond once a week which is controlling the algae. We’re very happy with the results

I had some reservations about purchasing this with "so-so" reviews. Have a (9 gal) stone garden fountain with a String Algae issue. My fountain incorporates simple water plants and naturally growing mosses (no fish). Concerned about plants and mosses being exposed to an algaecide. So with caution I dosed sparingly (1/2 strength) every other day. 6th day conspicuous improvement. String Algae dying and dead, BUT plants and mosses unaffected👍! I maintain my 'sweet-spot' dose upon every water added topping off. Dead pieces of algae have to be removed manually (adios!) Be PATIENT. Go slow when other plant forms are involved. (No fish here, so cannot advise🙏)

Completely Ineffective in controlling green algae. Even after overdosing, the algae is growing the next day. Waste of money.

I'll start with a disclaimer that the product does work in controlling algae in a pond where you have fish.With that said, you have to be EXTREMELY careful when measuring this out. You have to know how much water you have in your pond and use ONLY the recommended amount. If you are in a rush or if you guess, your fish will end up dead.This happed to me, and I acknowledge that it was my fault that I killed my ten year old fish when I was in a rush.I won't use it again; more of a safety precaution. I'll figure out other methods of controlling algae. So, I won't bash the product. It works. Just know that if you make a mistake that it will kill your fish.

Works great but only use what’s suggested per gallons. I used to much and almost killed my fish.
