MICROBE-LIFTOPCMD Oxy Pond Cleaner Treatment for Ponds, Fountains, and Water Gardens, Deep Cleans Light to Heavy Debris on Rocks, Waterfalls, and Planters, 8 Pounds

If you have any rocks in/around your pond at all, this product is a must have. Every other week I do a ~20% water change, I'll toss some on the areas I see algae and let it sit. A little goes a long way and it's very effective. I don't want to eliminate all algae because the koi eat it, but this reduces it to a level that beneficial bacteria surpass and the water is super clear in a day or so. Every pond is different, so results will always vary. But this is a must have for mine.

Nothing works better then the Oxy Pond cleaner. Pond never looked better. Be sure to follow directions as not to exceed what's recommended with adequate Pond Fountainand Aeration during its use.Amazing product.

I have a waterfall with no pond or fish. This works well keeping smell at bay. It does spike the Alkaline in the water like it warns you, which might be an issue for plants.

We have a small pondless waterfall under the trees in our backyard. This cleared it up very quickly and easily.

Did not perform as I desired. I wanted a product that could be added to the water, resulting in clean water and rocks.

I have been using this product, now for over three years and it works great.

It works fine breaking up the algae but don't nothing to stop it from returning. Maybe too expensive for weekly use.

simple to use

Have been using it for about 1 year now and it keeps the stream in my pond clear.
