Healthy Ponds 500,000 Gallon AquaSpherePRO

I tried using dyes, algaecides and a rake to clean up my mucky half-acre pond, but the results were temporary and spotty. These pond balls do the trick; I can see 3 to 4 feet down into my pond now. The water clarity is much improved, and there are no floating mats of algae. You can't skimp on dosing, though--I had to dose it every 2 to 3 weeks this year instead of monthly. That costs more, of course, but it worked! Just toss the ball into the center of the pond and walk away. Can't beat that for convenience.

Seems to work great. We have spent several years cleaning out pond & removing pond grass & algae. Put this in about 3 weeks ago. Does seem to be helping. Pond looks better than it ever has.

This ball worked great and fast. I put into the sump on a large water feature and it's done wonders.

I have only used this product over eight years with great success. Will continue to use this product.

Very satisfied with the product purchased for water treatment.

Seems to be doing the job as advertised. A lot of the muck is gone. Hopefully it will stay that way for a while.

I have a small farm pond that is covered with algae and has a fair amount of bottom sludge from leaves and grass. My pond is only about 30' in diameter and about 3' deep in the center. This product did absolutely nothing to help my pond. I feel like I wasted my money and am still looking for a solution. I used this in conjunction with a product that was supposed to help alleviate the bottom sludge issue. neither product showed any results.
