Frequently Asked Questions

1. How often should I replace the Black Sponge in my Delta 60 canister filter?
While the 30 PPI foam can be rinsed and reused multiple times during routine maintenance, replacing the black sponge every 6 to 12 months ensures that the pore structure remains firm and continues to trap debris effectively.

2. How do I clean my replacement filter sponge without killing beneficial bacteria?
Always squeeze out and rinse your filter sponges in a bucket of drained aquarium water during routine water changes. Using chlorinated tap water will instantly destroy beneficial nitrifying bacteria living inside the foam pores.

3. Where should the 30 PPI Black Sponge sit inside the Delta 60 media caddy?
The black sponge should always be placed at the beginning of the filtration flow path (bottom basket) to act as a pre-filter, preventing waste from clogging finer media stages.

4. Will this sponge fit other UNS Delta models like the Delta 30 or Delta 90?
No, the DELTA 60 Black Sponge is cut to fit the specific chamber dimensions of the Delta 60 canister filter media caddy. Always verify your filter model size before ordering replacement media.
