Aquarium Filter Intake Guard is used primarily for stopping fish, fry, shrimp and debris from being sucked into canister and hang-on filter intakes. This page lists the industries and assemblies where it is specified, the selection criteria that matter for each application, handling and installation practice, and the cases where a different mesh, screen or filter type is the correct choice. It is supplied to Aquarium hose sizes.

Typical Applications for Aquarium Filter Intake Guard

Where Aquarium Filter Intake Guard is specified and bought:

  • Aquarium brands: stainless intake guards.
  • Shrimp & nano tank keepers: fine guards that protect baby shrimp.
  • Pond filters: pump intake guards.
  • Aquaculture: hatchery intake screens.

How to Specify Aquarium Filter Intake Guard for Your Application

  • Diameter: Match the intake tube (12, 16, 22 mm).
  • Mesh: 60-mesh for shrimp; 30–40 mesh for fish.
  • Material: SS316 for fresh and salt water.
  • Standard: Quote Aquarium hose sizes and the size designation from the table on the product page, plus any value you changed in the technical drawing.

Handling & Installation Practice

  • Brush the guard monthly to keep flow up.
  • Secure it so it cannot slip off the intake.

Common Selection Mistakes with Aquarium Filter Intake Guard

  • A guard too coarse for fry and shrimp.
  • Letting it clog, which reduces filter flow.

Where Aquarium Filter Intake Guard Is Not the Right Choice

Not a replacement for sponge or floss mechanical filtration.
