Wakimizu Bakki Shower for Koi Ponds
The GCTek NishikigoiWakimizu Bakki Shower (the name translates to 'koi spring water') is a tiered trickle filter for koi ponds, available in polypropylene or stainless steel in five sizes. The top tier is a drip tray with an overflow that spreads water evenly, and the bottom level has a media support that holds the media above the openings for even flow. Multiple inlet/outlet unions sit on the back of the top tier to hide the pipework.
• Two Materials: Polypropylene (PP) or stainless steel (SS).
• Five Sizes: 15, 22, 40, 60 and 80, for ponds from 2,500 to 20,000 gallons.
• Even Distribution: Drip tray top tier with overflow.
• Hidden Plumbing: Multiple inlet/outlet unions on the back top tier.
• Outlet Styles: Waterfall and pipe fitting outlets; 3″ on the 60 and 80, 2″ on the others.
