Pond Filter Weir Waterfall Box

  • Strong injection mold housing
  • DIY (do it yourself) design: water fall or bio mechanical filtration system for the pond
  • Very easy installation and connection to PVC fitting
  • Two type of weir: Weir I and Weir II (with W flow shape), PVC pipe and flexible pipe or tubing
  • Can have a multi-layer function
  • For filtration can use brush, sponge, ceramic ring and bio balls
  • WEIR II comes with 2 water plate for indoor and outdoor usage
Use Weir I & II for water fall:
Weir  I & II are designed with simple way to make water fall feature of 17" wide water fall curtain to the pond and create turbulence to increase the oxygen level.  Weir I & II are the same shape.  The only different thing is that Weir II has a extra water plate which water can flow along the W flow shape mold.  Weir I & II can be hidden behind rocks to create a natural appearing water fall.  When you install Weir I & II to make water fall, make an exact water level that water flows evenly over the fall.  When you want to make stair step pattern for cascade, install two or more Weir just like stairs.
Use Weir I & II for Filtration System:
Weir I & II can be used also to offer bio mechanical filtration that supports the growth of beneficial bacteria.  For filtration system, bio-balls, ceramic rings, wire brush and foam filter etc. should be filled in the weir.  All are necessary things for biological and mechanical filtration
