Aquarium Intake Filter Guard / Snail & Fry Protector

This is a two-part aquarium intake filter guard designed for external or internal aquarium filter intake pipes.

The main body is pushed onto the intake pipe, while the top cap screws onto the main holder. The model is designed with vertical openings that allow water to flow into the filter while reducing the risk of small fish, fry, shrimp, snails, or larger debris being sucked directly into the intake.

The model is printed from PETG, which is a better choice than PLA for aquarium use because it is more resistant to water and temperature changes.

This is not a biological filter by itself. It works as a protective intake guard / pre-filter cover for the existing aquarium filter system.

Notes:
Before using the part in an aquarium, rinse it well with clean water.

Do not paint it and do not use unknown coatings, glue, or resin on the part before placing it in the aquarium.

Check that the intake openings are suitable for the size of your fish, fry, shrimp, or snails.

Make sure the guard does not reduce the water flow too much. If the filter flow becomes weak, clean the guard from debris.
