Frequently Asked Questions
Q: Which canister filter models are these aquarium filter pads compatible with?
A: These filter pads are custom-designed to fit SunSun GRECH 304AB, 404AB, and 704AB canister filters. They are not guaranteed to fit other models without trimming.
Q: Can I reuse these aquarium sponge filter pads after cleaning?
A: Yes! These high-density foam pads are fully reusable. Simply rinse them with aquarium water (not tap water, to preserve beneficial bacteria) during your regular maintenance routine and place them back in the filter.
Q: What is the difference between the blue and white layers?
A: The dual-layer design uses different densities — the coarser layer captures larger debris and particles first, while the finer layer catches smaller waste, providing a two-stage mechanical filtration process for cleaner aquarium water.
Q: How often should I clean or replace these filter pads?
A: This depends on your tank's bio-load, but most aquarists rinse their filter pads every 4–6 weeks. Replace the pads when they begin to deteriorate or can no longer be cleaned effectively. Having a 4-pack on hand means you always have a fresh pad ready to swap in.
