Product: Filters - Gravity Flow

Dirty water passes through filtration media to create effective biological filtration. Gravity Flow filters usually sit higher than your waterfall display or above your bog and the water flows from the filter back into your pond. The water will be filtered through it and gravity itself will allow the water to fall; bear in mind these can’t pump water up so you can’t let them flow over long distances unless you keep the filter higher than the return.

Our gravity flow filters use biological media to convert impurities, and we have many different styles to choose from to meet the needs of every pond.

In our collection of gravity flow filters, you'll find Matala, Laguna and FishMate filters, giving us a well-rounded selection with both UV-enhanced filters and standard biological filters included in our inventory. All of the gravity flow filters that we carry feature quality craftsmanship and are trusted names in pond care. With our gravity filters, you can maintain ponds from 500 to 2,600 gallons in size.
