About this product
Twelve pre-filter sponges come in this pack, each measuring 3.4" long and 2" across with a 0.83" hole through the middle. The sponge slides onto the water inlet of a fish tank filter, where it keeps shrimp, fish fry and weaker inhabitants from being drawn in. Pawfly makes the foam in black and lists it for freshwater and marine aquariums.
Fitting the sponge on a filter intake
A 0.83" diameter opening accepts the intake, and the sponge is pressed onto the fish tank filter's water inlet. Directions from the manufacturer call for swapping the pre-filter sponge for a new one rather than cleaning and reusing it.
Checks before you buy
Measure the intake tube on your filter first: the sponge fits a tube that matches its 0.83" opening, and the 2" width sets how far it sits out from the inlet. The sponge is listed for freshwater and marine aquariums, so a tank outside those two types is not covered. Its body runs 3.4" long, which is the space it needs around the intake.
Foam body and how it sits in the water
The foam is soft and has high elasticity, so the sponge grips the inlet it is pushed onto. Its inner structure is described as fluffy, and water continues to pass through it at its normal flow.
The sponge catches debris, leftover food, waste and plant matter before they reach the filter, and it also keeps that material out of the filter itself. The same layer of foam stands between small tank inhabitants and the intake, so they are not pulled inside.
What is in the pack
- Twelve pre-filter sponges, model Pawfly-2185-BK
