The Atlantic Water Gardens GK600 Gate Keeper is a simple, durable accessory that clips into the 6" skimmer weir to keep fish from entering the skimmer while allowing leaves and debris to pass. Designed for use with Atlantic Big Bahama skimmers, the GK600 reduces accidental fish loss and helps the skimmer focus on surface debris.

  • Direct clip-in design mounts to the skimmer weir door without tools for fast installation and removal.
  • Compatible with Atlantic PS3900, PS4000 and PS4600 (6" weir) skimmers; fits standard 6-inch weir openings.
  • Allows surface debris and leaves to pass through while deterring fish from entering the skimmer cavity.
  • Durable construction resists pond water — stainless steel clips with polypropylene brush components.
  • Low-maintenance: periodic rinsing or light brushing keeps flow unrestricted and prevents buildup.
  • Compact, replaceable design works with additional brush panels or Matala filter products for improved mechanical filtration.

Use the GK600 as a preventative measure to protect fish and improve debris collection. Inspect the gate keeper with regular skimmer maintenance and remove debris as needed; replacement parts are widely available from Atlantic authorized dealers.
