CrystalClear AlgaeOff Pond & Water Garden Scum Cleaner, Waterfall & Rock Slime Remover, String Algae Killer, Green Stain Treatment, EPA Registered Algaecide, Plant, Koi Fish, Bird & Pet Safe, 25 lbs

Great product. Received undamaged.

My pond is about 1/3 acre and about 15 feet deep, so I had to use the whole bucket. It took a few days and seems to be working. There is still a little algae left but compared to how much was in there before I consider it a small victory. I would recommend this product

This is the absolute best my water feature has ever looked. Small amt. Really cleared up the rocks and water. This stuff is great

Don't purchase. Says safe to fish and birds on advertisement. When you peel the disclaimer off the bucket. It states dangerous to birds and fish. False advertisement and a non-refundable item.

this product is priced right and does a good job

I bought this hoping to kill the algae in my pond. I was really impressed with how quick it killed it. It was almost immediate, and I spread it using a grass seed spreader. I ended up buying another bucket of it for my other pond. I would highly recommend this product.

This product can be spread by hand, and will not hurt your fish or frogs. You need to use it more liberally than instructions, imho. I buy the large bucket, which is expensive. I use it spaced between beneficial bacteria products from the Pond Guy. Muck Away, Pond Clear, and Eco Boost. All expensive too. And pond dye to block sun from growing algae. It is basically peroxide. If used in waterfall, make sure it’s wet, right after you turn it off.

Works for short term & needs multiple applications
