Inspect the fit
Look for gaps around the intake where a tiny shrimp could pass. Make sure the sponge or mesh stays attached when the filter operates.
Choose material designed for aquarium use and compatible with the specific filter. A loose guard can create a different hazard or reduce circulation.
Check flow regularly
A prefilter traps debris and may need cleaning. Reduced flow can indicate clogging, so inspect it as part of normal equipment checks.
Clean according to the manufacturer’s instructions and avoid sterilizing biological surfaces. Preserve media that supports the filter’s established operation.
Recheck after maintenance
Confirm that the intake remains fully covered after reassembly and that water movement has returned. Look for young shrimp on the sponge before handling it.
If the filter is not drawing water properly, resolve that issue before leaving the aquarium. Equipment protection and circulation must work together.
