Standard Wide-mouth Black In-wall skimmer SB265 (Liner / Concrete)

 
Surface Skimmers are an important piece of equipment for any pond, but more essentially for the Koi Pond, if you are planning to build a Koi pond make sure fit one of these into your construction process.
Pond skimmers are easy to install. They will collect any debris that falls onto the surface of your pond or leftover food into a collection basket before it has chance to sink to the bottom and starts breakdown and effect the quality of your water.
