Seachem Tidal 55 Foam – Replacement Filter Sponge 2 Pack
Keep your Seachem Tidal 55 Power Filter operating efficiently with the Seachem Tidal 55 Foam 2 Pack. These genuine replacement foam sponges are shaped specifically for the Tidal 55 media basket and provide dependable mechanical filtration without trimming or modification.
The foam captures fish waste, uneaten food, plant debris, and other larger particles before they travel farther through the filter media. Regular cleaning helps maintain strong water flow, supports efficient filtration, and keeps aquarium water looking clear.
Each package contains two reusable foam sponges, making it convenient to keep a replacement available for routine filter maintenance.

Compatible Filter
This replacement foam is designed specifically for the Seachem Tidal 55 Power Filter. The Tidal 55 is rated by Seachem for aquariums up to 55 US gallons and has a maximum flow rate of approximately 250 gallons per hour.
The foam should not be assumed to fit Tidal 35, Tidal 75, Tidal 110, or filters produced by other manufacturers. Each Tidal filter model uses foam sized for its individual media basket.
How the Foam Works
The Tidal 55 uses a bottom-to-top water-flow design. Aquarium water enters through the bottom of the filter basket and passes upward through the installed filter media.
The foam acts as the primary mechanical filtration layer, catching larger debris before it can accumulate throughout the remaining filter media. This helps protect biological and chemical media from becoming clogged as quickly.
While beneficial bacteria may naturally grow on the foam’s surface, Seachem Matrix is the primary biological filtration media supplied with the Tidal 55 filter.
How to Install
- Unplug the Tidal 55 Power Filter before beginning maintenance.
- Remove the filter lid and lift out the media basket.
- Remove the old foam sponge from the bottom of the basket.
- Place the clean replacement foam into the same position.
- Return Matrix and any additional filter media to the basket.
- Reinstall the media basket and filter lid.
- Confirm that the basket is seated correctly before restarting the filter.
No trimming, shaping, or modification should be required when installing the correct Tidal 55 replacement foam.
How to Clean the Foam
Rinse the sponge during routine filter maintenance whenever it becomes visibly dirty or water flow begins to decline.
For established aquariums, gently squeeze and rinse the foam in a container of water removed from the aquarium during a water change. This loosens trapped debris while reducing exposure to untreated chlorinated tap water.
Do not scrub the foam aggressively or use soap, bleach, household cleaners, or disinfectants. Cleaning chemicals may leave residues that are dangerous to aquarium livestock.
When to Clean the Foam
Cleaning frequency depends on the aquarium’s stocking level, feeding routine, plant debris, and overall waste production. Heavily stocked aquariums may require more frequent cleaning than lightly stocked systems.
Inspect and clean the foam when:
- The blue Tidal maintenance indicator rises
- Water flow becomes noticeably weaker
- The sponge contains visible debris
- Water begins bypassing the filter basket
- The aquarium has recently experienced heavy feeding or plant trimming
- Routine water-change maintenance is being performed
When to Replace the Foam
The Tidal 55 foam does not need to be discarded simply because it has been used for a few months. With proper care, the sponge may be cleaned and reused repeatedly.
Replace the foam when it:
- Begins tearing or breaking apart
- Becomes permanently compressed
- No longer returns to its original shape
- Cannot be cleaned sufficiently
- Allows water to bypass damaged areas
- Has been contaminated by soap, chemicals, or other unsafe substances
Avoid replacing every piece of established filter media at the same time. Keeping mature biological media in the filter helps preserve the aquarium’s beneficial bacterial population.
Using with Other Tidal Filter Media
The Tidal 55 media basket may hold multiple types of filter media. The replacement foam can be used with Seachem Matrix, activated carbon, Purigen, phosphate-removal media, or other aquarium filter media appropriate for the system.
- Seachem Matrix: Provides high-surface-area biological filtration
- Seachem MatrixCarbon: Provides chemical filtration for dissolved organic waste and discoloration
- Seachem Purigen: Helps remove soluble and insoluble organic impurities
- Specialty Media: May be added when the aquarium has a specific filtration requirement
Do not overpack the media basket. Water must be able to pass through the foam and remaining media without excessive restriction.
Freshwater Aquarium Use
The Tidal 55 replacement foam is suitable for freshwater community aquariums, planted tanks, cichlid aquariums, goldfish systems, and other freshwater setups using the Tidal 55 Power Filter.
In planted aquariums, the foam helps capture loose leaves, plant fragments, and suspended debris following trimming and aquascaping maintenance.
Saltwater Aquarium Use
The replacement foam may also be used in marine and brackish aquariums equipped with a Tidal 55 filter. Regular cleaning is especially important because trapped organic debris can break down and contribute to aquarium nutrient levels.
Rinse the sponge frequently enough to remove captured waste before it accumulates excessively.
Filter Maintenance Tips
- Unplug the filter before removing the media basket
- Clean the foam when flow declines or the maintenance indicator rises
- Use removed aquarium water for routine rinsing
- Never clean the foam with soap or household chemicals
- Avoid replacing all biological media at the same time
- Keep the media basket from becoming excessively packed
- Inspect the foam for tears and permanent compression
- Keep the second sponge clean and dry until needed
- Continue testing aquarium water during and after filter maintenance
Important Aquarium Care Note
The replacement foam supports mechanical filtration but does not replace biological filtration, water conditioning, water testing, or regular aquarium maintenance.
A dirty or clogged sponge can reduce water flow through the filter. However, rapidly replacing all established filter media may remove beneficial bacteria and contribute to ammonia or nitrite problems.
Clean and replace filter components gradually whenever practical, especially in established or heavily stocked aquariums.
Frequently Asked Questions
What filter does this foam fit?
It is designed specifically for the Seachem Tidal 55 Power Filter.
How many sponges are included?
Each package contains two replacement foam sponges.
What type of filtration does the foam provide?
The foam provides mechanical filtration by trapping detritus and other larger particles.
Does the foam provide biological filtration?
Beneficial bacteria may colonize the foam, but Seachem Matrix is the primary biological media supplied with the Tidal 55 filter.
Is the foam reusable?
Yes. It may be rinsed and reused until it becomes damaged, permanently compressed, or difficult to clean.
How often should I clean the foam?
Clean it whenever it becomes visibly dirty, water flow declines, or the Tidal maintenance indicator rises. The exact schedule depends on the aquarium’s waste load.
How often should I replace the foam?
There is no required three-to-six-month replacement schedule. Replace it based on physical condition and performance rather than age alone.
Can I rinse it under tap water?
Using water removed from the aquarium is preferred when preserving bacteria on established media. Untreated chlorinated tap water may harm beneficial bacteria.
Can I clean the foam with soap?
No. Never use soap, bleach, detergent, or household cleaning products on aquarium filter media.
Can the foam be used with Matrix?
Yes. The foam captures larger debris while Matrix provides biological filtration.
Can it be used with Purigen or activated carbon?
Yes. The Tidal media basket can hold the foam along with compatible chemical and biological filter media.
Is this foam safe for freshwater aquariums?
Yes. It is suitable for freshwater and planted aquariums using a Tidal 55 filter.
Is it safe for saltwater aquariums?
Yes. The Tidal 55 and its replacement foam are suitable for freshwater and saltwater environments.
