Coldwater Blocks 24 Blocks

Does a good job helping to keep my pond clean. Winter, Spring, Summer or Fall. I have a pretty big pond (3000+ gallons) with a lot of fish and this helps keep the muck cleaned up.

This cold bacteria loves to work hard . After a few days - like magic how clean my pond got.

it isn't clearing the water up and it's been 1 month of using the product.

It clear up my water. Will order it again.

Great product at a great price. Works really well.

My pond is about 1300 gal, 50? smallish goldfish, frogs and 10+ years old. I've tried other bio additives, filters, UV Sterilizers, pond cleaning services. None work so well and as quick as a couple blocks of this product. Soon as I use up this can of blocks I'll be buying more. Thanks Pond Force!
