FAQ
How often should I change the media?
Replace the fine/white polishing pad every 2–4 weeks (or sooner once clogged). The coarse/blue pre-filter can be rinsed and reused several times before replacement — swap it when it tears or stops flowing well.
Can I use these in saltwater?
Yes — mechanical filter media is fully reef-safe. Rinse new pads in tank water before installing to remove any loose fibers.
Do they fit other Aquatop CF models?
These specific variants are sized for the CF400. If you run a CF-300 or CF-500, check the Aquatop part number before ordering.
Should I rinse them before installing?
Yes — a quick rinse in dechlorinated water (or used tank water) clears loose fibers and seats the pad evenly in the canister tray.
