Description:
A filter intake sponge known as a pre filter sponge fits over the intake pipe of your filter and acts as a pre-filter, catching debris, detritus, and fine particles before they enter the filter body.
This does two things: it reduces the amount of waste your mechanical filter media has to process, reducing the amount of debris reaching the main filter media and potentially reducing how frequently it needs to be cleaned and protects shrimp, fish fry, and small juvenile fish from being drawn up into the intake.
Unlike an intake guard, which stops livestock from entering the intake but does no filtering, an intake sponge actively pre-filters the water as it passes through. Over time the sponge also builds up a colony of beneficial bacteria, adding a small but useful biological filtration element right at the point of intake.
This size suits 20mm (2cm) intake pipes.
Pack of 10.
Check your filter's intake pipe diameter before ordering to ensure the correct fit. Also available in a small size for 10mm intakes.
Suitable for freshwater and saltwater aquariums, canister filters, HOB filters, shrimp tanks and breeding setups.
Product Features:
- Filter intake sponges are ideal for preventing fry, shrimp and small fish from being sucked into the filter, providing an added layer of protection in breeding setups.
- Filter sponges also act as a pre-filter, trapping large particles so they don't clog your filter.

How the Pre-Filter Sponge Compares
🧽 Filter Intake Pre-Filter Sponge
- 🛡️Protects Small Livestock: The sponge helps prevent shrimp, fry and small juvenile fish from being drawn directly into the filter intake.
- 🧹Traps Debris Before the Filter: Captures larger debris, detritus and fine particles before they reach the main filter body.
- 🔧Reduces Mechanical Filter Load: Pre-filtering debris at the intake can reduce the amount of larger waste reaching the filter's primary mechanical media.
- 🦠Provides Additional Biological Surface: The sponge can become colonised by beneficial bacteria, providing an additional biological filtration surface.
- 💧Filters While Protecting the Intake: Combines livestock protection with active mechanical pre-filtration in one simple attachment.
🛡️ Basic Intake Guard
- 🛡️Protects Livestock: A guard helps prevent larger livestock from entering the filter intake.
- 💧Allows Water Through: Openings allow aquarium water to enter the filter while keeping larger objects away from the intake.
- 🧹Limited Particle Filtration: Larger openings allow many smaller particles and fine debris to pass through into the filter.
- 🦠Little Additional Bio Surface: A basic guard does not provide the same sponge surface area for beneficial bacteria to colonise.
- 🔧Primarily an Intake Barrier: Designed mainly to protect the intake rather than provide an additional stage of mechanical filtration.
A simple, inexpensive upgrade that extends the life of your filter media and adds a layer of protection for small livestock. Particularly useful for shrimp keepers and breeders who want the pre-filtering benefit alongside the physical protection of keeping small creatures away from the intake.
Rinse intake sponges in old tank water periodically to remove accumulated debris and restore flow. Never rinse in tap water as chlorine will harm the beneficial bacteria that build up on the sponge over time. Replace when the sponge begins to break down or can no longer be cleaned effectively.
Frequently Asked Questions
What is a filter intake sponge used for?
A filter intake sponge fits over your filter's intake pipe and acts as a pre-filter. It traps debris and fine particles before they enter the main filter, while also helping prevent shrimp, fry and small fish from being drawn into the intake.
What size filter intake sponge do I need?
Choose the sponge based on the diameter of your filter's intake pipe. The Large size is designed for 20mm (2cm) intake pipes, while the Small size is designed for 10mm intake pipes. Always measure your intake pipe before ordering to ensure the correct fit.
What is the difference between an intake sponge and an intake guard?
An intake guard primarily prevents fish, shrimp and other livestock from entering the filter intake. An intake sponge provides this protection while also filtering the water, trapping debris and fine particles before they reach the main filter.
Are intake sponges suitable for shrimp and fry?
Yes. The sponge helps prevent shrimp, fish fry and small juvenile fish from being drawn into the filter intake, making it particularly useful for shrimp tanks and breeding setups.
Can a filter intake sponge reduce how often I clean my filter?
It can help reduce the amount of larger debris and waste reaching the main filter media, which may reduce how frequently the main filter needs cleaning. The intake sponge itself should still be cleaned regularly as it collects debris.
Does the sponge provide biological filtration?
Yes. As the sponge is used, beneficial bacteria can colonise its surface, providing an additional source of biological filtration. Its primary purpose, however, is mechanical pre-filtration and intake protection.
Can I use these sponges on canister and HOB filters?
Yes. They can be used on suitable canister filter and HOB filter intake pipes, provided the sponge's internal opening matches the diameter of the intake pipe.
Are these filter intake sponges suitable for freshwater and saltwater?
Yes. They can be used in both freshwater and saltwater aquariums.
How do I clean a filter intake sponge?
Remove the sponge from the intake and gently rinse or squeeze it in removed aquarium water to remove trapped debris. Avoid cleaning it too aggressively, as this can remove beneficial bacteria from the sponge.
How many filter intake sponges are included?
Each pack contains 10 filter intake sponges in the selected size.
