Aquascape 96022 Algaecide for Pond, Waterfall, and Water Features, 8-Ounce

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

My pond was inundated with algae. Within three days it was nearly gone. Kept working for a week. Pond is clear now.

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

Careful when using this. All algicides will raise the pH but so far I like this one best. It gets rid of algae fast so always use as little as possible, I actually use half doses with pH down to get rid of it slowly. Good value, packaged well didn't leak arrived fast.

Even though it doesn't work so well in cold weather it still does it's job. I have an approximate 4500 Gal. Pond and have a waterfall pump and filter and a separate pump aerating the water and they are running 24/7. Placing this in the water every 3 days until pond is clear from this green water single cell algae, is slowly doing it's job. Have been finding small clumps of algae and the water in the pond ie beginning to clear up. Have been using this product for 3 weeks now but water is still green, beginning to see the Koi. It works, but slower than I thought it would.3/3/22 Been using this for a month now, since it's been cold in Orange County, it's working a little slow, but it is working. When I first started using this, I couldn't see our Koi, now I can see them below the surface. Water is still not clear of green water algae, but it's getting there. The submersible pump I'm using to aerate water more is always getting clogged with algae clumps so I know the product is working. Hopefully, won't be too much longer before the green water algae is gone?

Kills fish:I didn’t even use a full dose and it killed all my fish in one day!

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.

I applied this product per instructions listed on container to clear up algae in my pond that was making the water green. My pond is about 12,000 gallons with a waterfall feature. I am trying to get it clear so I can see my koi. I continued to increase the dosage after initial couple doses showed no effect. Ultimately I used all 2 1/2 gallons, along with another 2 1/2 gallons of a similar product and did not really see any clearing of the water.
