Review: Algae cleaner - Was a bit skeptical but WOW, this has worked better than anything else I’ve tried so far for our waterfall… easy dosing and within 3 days noticed a huge improvement.
Review: Works to suppress algae - I had a swimming pool that 11 ducks moved into and created a mess with waste and since I stopped using chlorine, a ton of algae. Although it's hard to say what was waste and what was algae at some point, the product clearly works. The water color went from solid to clear in a matter of a few weeks. You have to use double the dose (I suggest triple) . Ducks drank directly from the treated water and no health concerns which was my biggest worry. Better if you start using it right away before the algae gets out of control.

- Faster Than Pellets, Cleaner Than Bales -- Enjoy the benefits of barley straw without the mess and without the wait. Extract is faster than barley pellets and cleaner than barley straw bales.
- Easy Application, No Mess Formula -- Simply measure and pour into pond water. No water use restrictions. Use treatment all year to improve water quality and to maintain beautiful, crystal-clear water.

### ⭐⭐⭐⭐⭐ Algae cleaner

### ⭐⭐⭐⭐⭐ Works to suppress algae
*by S***Y on September 18, 2024*

### ⭐⭐⭐⭐⭐ Awesome- works great!
*by N***1 on May 10, 2025*

Excellent product works exactly as described- used for my algae- ridden fountain in Arizona. Quickly cleaned up the water, made pump more efficient (since algae wasn’t clogging it up), AND rabbits and birds are still drinking out of it!
