Natural and balanced

posted 6 years ago

Love that this filter enhances and creates a balanced bio-environment by not removing positive bacteria

Pros: very helpful to keep good bacteria in and the bad out

Cons: kinda noisey

Great Product

posted 6 years ago

We got some of these for our pond in our yard, and it works so much better than the traditional pond filters. We were very, very pleased with the results.

Pros: great for ponds, too

Cons: none
