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

This product has done a good job of suppressing the growth of algae in our fountain without killing the surrounding plants. Seemed od to me that Amazon would not ship the gallon size to my location but would ship 2 quarts?

We have a coi pond approximately 12 feet x 5 feet x 2.5 feet deep. Eight cascading waterfalls. String algae begins as soon as the weather warms. Using this product, along with regular maintenance, has eliminated the algae problem completely. Fish and frogs are thriving.

It took a LONG TIME to arrive after ordering. Third-party seller, so not really Amazon's fault. To their credit, we received regular updates on the delays, with easy options to cancel the order or refuse the package. Just be aware of the possibility.I added the first dose of the algaecide yesterday, after a thorough cleaning of the water feature. I'll report back and adjust the rating if the results are less than great.The product: Easy to open and pour into a measuring spoon. Recommendation for use varies between every five and seven days. The labels are EPA blessed, so I'm a little surprised at the ambiguity. We'll know easily in a few weeks if it works or doesn't. The pump in the little water feature lets me know pretty quickly when the filter gets fouled with algae growth.

This stuff is amazing! Cleared up the water if out fountain in 2 days

Absolutely do NOT buy this product,I follow the directions precisely as I had very sentimental fish that was given to me by a friend who just passed away. This completely killed every single last aquatic plant and fish in my pond. Within hours. Even after trying to empty the pond and attempting to transfer any fish that moved, I was not able to save even one out of over 20 fish. This is so disheartening, I repeat do not buy this product.

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.

A few dollups to this stuff keeps my pond nice and clear

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.
