CaddyStack™ Sponges - Pair of 2

The CaddyStack™ Sponge - Pair of 2 is a reusable sponge add-on designed specifically for the CaddyStack™ Modular Filter Tower.

Each sponge features 3 layers of different density, helping create a balanced flow path while catching debris as water moves through your CaddyStack™. The layered design gives you a simple mechanical filtration option that can be placed inside the short tubes or short cages of the corresponding CaddyStack™ size.

These are made for reefers and aquarium keepers who already use the CaddyStack™ and want an easy, reusable sponge option for extra filtration flexibility. Instead of only relying on filter floss or loose media, the CaddyStack™ Sponge gives you a clean, drop-in solution that is easy to remove, rinse, and reuse.

Each pair is printed in the official Printed Reef clear/blue colorway.
