Aquarium Pre-Filter Sponge Intake Cover for Fish & Shrimp (20mm)
Aquarium pre-filter sponge intake cover sized at 20mm, a shrimp and fish guard for filter intakes of that diameter.
Price range: See on Amazon
What we liked
- + The 20mm size is clearly stated, so matching the intake is simple
- + Stops shrimp, fry and plant debris from entering the filter
- + Keeps impellers cleaner, which cuts down on rattle and wear
Trade-offs
- - Only suits intakes near 20mm, so thinner tubes need a different cover
- - Foam density is basic, so check it suits your filter's flow rate
