Ultimate Pond Bacteria, Outdoor Pond & Lake Natural Beneficial Bacteria Treatment, Aquatic Odor Reducer & Sludge Digester, Fish, Plant, & Livestock Safe, Easy Dosing Liquid, 1 Gallon Bottle

I found this product effective for keeping the floating algae under control in my 1/4 acre pond. But I found it a hassle to apply. I did not want to pour an entire dose in one spot, so I would make myself go all the way around the pond to distribute. I have steep slopes that are often muddy, so getting close enough to the water multiple times was a hassle. Fortunately, this same vendor offers a similar product in powder packet form. I just love that product because I can quickly and easily toss a couple of water soluble packets out into the pond.

Works well to clear the water in my backyard pond. Thanks

We have this on quarterly order for our two ponds. It works great! The water becomes very clear!

I usually do not write reviews but I'm so impressed that this actually works! I tried to upload photos but couldn't for some reason. Our quarter acre pond was solid green with algae a week ago. We did one treatment so far (used 1 quart) and everyday watched the algae gradually dissappear. Now, there is very little left. We still need to do another treatment as the directions state but I'm so happy and our ducks are happy!

Saw no effect on sludge

Works great for my pond 30’x40’x6’

As advertised

My 8000 Gal Koi Pond in full sunlight developed serious algae problem. Tried diatoms, Cu, bacteria concoctions, sludge removers (no sludge), dyes, - all no good. Pond got worse. Algae need sun, so I installed sunblocker screens, Royal Shade, 6' X 50' cut in half. In one day, pond was clearer.
