Healthy PondsAquasphere Pro Biodegradable Pond Treatment, Treats up to 1,000 Gallons

I could see a significant improvement in the water clarity of my small goldfish pond several days after tossing the biodegradable globe in. The fish remained healthy.

I put 2 in each pond no more algae amazing

Very small yet to see if it works out

The product was easy to use - just threw it in the pond, watched it float a few minutes and then it was gone. The pond was crystal clear the next day but then it became murky again right away. Basically I can't say if the product has worked or not but I thought it was worth the try!

I put this in my pond a week ago and show no difference. My pond is still very green. Will not get again

I got this hoping to help fix the pond that was on our property. They work great they man that we had come out to look at it said I am doing everything right the pond was just to far gone to save so I have to have it dig out. But he said to still use these after it will keep my pond in usable condition. He also said the water is perfect just the cattails are to far out of control and the roots have takin in.

Tried many things but this stuff actually works

Placed this mini death star in my small pond and the algae got thicker after several weeks. I have about a 350 gallon pond with pump and filter and clean the filters often and it still looks like I have a swamp growing even with the pH of the pond about normal. Not my intended plan. It says it can take up to 6 weeks for this product to work, and yet each sphere only last up to a month. Not for what it cost (over $20) and lack of performance would I shell out money again for a second one.
