How the Waterfall Filter Works:
- Fiber Mat Pond water is pumped into the bottom of the filter. It rises upwards through a fiber mat, which traps suspended dirt and debris.
Biological Filtration - Lava Rock in Mesh Bag:
- Beneficial bacteria will naturally colonize on the rough surfaces of the lava rock (not included) and convert harmful pollutants in the pond water into relatively harmless nitrates. Nitrates are absorbed by aquatic plants and can also be removed from the pond through partial water changes. This process is knows as the Nitrogen Cycle.
Installation Tip to Prevent Leakage:
- It is important that all water from the spillway falls directly into the pond, stream or onto a piece of pond liner that drains the water back in the pond. Even though the spillway has a triple drip edge, water can splash on the rocks and bounce out of the pond.
To Prevent Water Loss:
- Place a piece of pond liner underneath and up the back of the filter. Be sure the sides and back of the liner slope downwards towards the pond. The liner should overlap the water's edge so any water spilling onto the liner will flow back into the pond. Stack stones and/or backfill with soil to hide the filter and the liner material.
