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

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.

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.

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.

Fish pond algae control worked great when used as directed and did not harm the pond fish.

Completely ineffective on the hair algae in my pond. A total waste of time and money.

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'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.
