Which Delta UV Series Is Best For Koi Pond Applications?
While all Delta UV series are applicable for Koi Pond installations, the Elektra ProT EP series has become the “Cadillac” of the Koi industry over the past four years. The EP Series is 100% stainless steel construction and carries the longest Limited Warranty (5 years) of all Delta UV units. Originally designed specifically for Koi pond application, the EP units feature a low pressure switch that is compatible with bead filter installations, and a generous 2 inch (63 mm) inlet/outlet unions that provide ease of installation and removal for maintenance of the quartz tube (periodic cleaning). If your installation is a salt water installation, then we recommend the all polymeric (plastic) E Series as the harsh environment of a salt water installation is better served when no metal is present to cause corrosion of the vessel. When your pond has the EP series installed, you have selected the best UV unit for the Koi pond enthusiast .
