Introducing the Blue Thumb Pond System
In our pond kit systems, the filtration consists of a mechanical skimmer filter and biological waterfall filter. The skimmer will pre-filter the water and house the pump; it will also skim debris from the water’s surface to prevent the accumulation of debris on the bottom of the pond.
The waterfall box provides surface area for beneficial bacteria to colonize and remove excess nutrients from the water thereby keeping your pond clean and clear.
Rocks and gravel serve to protect the pond liner from UV light. They also provide additional surface area for bacteria to colonize and break down excess nutrients, making your pond look natural.
