Aquarium Co-Op Replacement Fine Sponge for Easy Flow Sponge Filter

A fine replacement sponge for the Aquarium Co-Op Easy Flow sponge filters. Exactly the same sponge that ships on a new filter, sold on its own so you can swap one out rather than replace the whole unit. Keeping a spare on the shelf also means you can put a clean one straight on and take your time washing the old one.

Features

• Fine, water-polishing sponge. At 40 ppi it catches the finer particles the coarse sponge lets through, which is what you want on a fry or shrimp tank.
• Shipped full sized, not vacuum packed. Aquarium Co-Op do not compress these. Vacuum packing crushes the cell walls, and the sponge never fully recovers its shape or strength.
• A direct replacement. Identical to the sponge supplied with their filters, so nothing else needs changing.
• Fits most sponge filter bases. Not just Aquarium Co-Op ones. If you are running another brand, bring the base in and we will check it against the sizes.
• Keeps your bacteria. Swap one sponge at a time and rinse the old one in tank water rather than replacing both at once, and you will not lose the colony.

Sizes

Match the size to the filter you already own. If you are unsure, measure the old sponge or bring it in.

Frequently Asked Questions

Can I use this on an intake instead?
Aquarium Co-Op point you at their closed end pre-filter sponges for that. These are open ended and made to sit on a sponge filter base.

Will it fit a different brand of sponge filter?
Usually. They are sized to the common standards. Bring the base in and we will check.

How often does a sponge need replacing?
Not often. Rinsed in tank water they last years. Replace one when it starts falling apart or will no longer rinse clean.
