The Helix Settlement Tank is designed specifically for Koi ponds with a bottom drain. It cleans heavy debris (leaves, sticks, stones, muck) from your water before it ever enters your pump and filtration system and damaging your pump. The Helix Settlement Tank acts as a pre-filter for the bottom drain, providing an effective and economical way to protect your pump, improve pump efficiency, extend pump life and make cleaning your pond much easier. The Settlement Tank is set up to be easy to disassemble for easy access for vacuuming, pumping, siphoning or draining larger debris. The debris filter still allows small particles to pass through, which is why the Settlement Tank is specifically intended for a bottom drain pre-filter (not a substitute for a mechanical pond filter).

USE of the Helix Settlement Tank

  • These tanks do not come pre-drilled as they have numerous points of entry with uses that depend entirely on the positioning of the tank and other equipment
  • The settlement tank should be located as close as possible to the edge of the pond
  • The water level inside the tank will be exactly the same as the water level in the pond. Position the tank so that “overflow” to pump will be safely underwater
