Pre filter sponge for lily pipe intake

Recommended Posts

Im looking for a intake sponge for a lily pipe intake but I can't find any. Is there a specific brand that will fit a 17 mm outer dimension for it? I also need it to be fine enough so shrimplets don't get sucked in.

Can you share any photos? Dimensions? 

If you buy your own sponge in bulk, and are handy at cutting, you maybe could fashion your own to fit.

Its about 11 inches long and im trying to look for something already cut out.

Without more dimensions, it is not easy to understand what you’re looking for.

All manner of sizes of these are available online for sale…


Just search “Pre-filter Sponge” and you can generally get whatever you desire.

OP wants a sponge to fit the tube on the intake of their lily pipes. it should be 5/8 inch (16mm) inner diameter and about 3 to 4 inches (75mm to 100mm) tall.


I think 3 to 4 inches tall is good

I found one which is the fluval edge prefilter sponge. Is that fine?
