AQUANEAT Replacement Canister Filter Pads for SUNSUN HW-304B/404B/704B/3000 CF500

Elevate aquarium filtration with the AQUANEAT Replacement Canister Filter Pads, designed to fit SUNSUN HW-304B, HW-404B, HW-704B, and 3000 CF500 canisters. This multi-stage kit combines coarse, medium, and fine sponge pads with white floss pads to target a range of particle sizes while preserving steady water flow for a healthier tank aesthetic.

What is included

• One coarse blue sponge pad for robust debris capture
• Two green medium sponge pads to handle mid-sized particles
• One black fine sponge pad to trap smaller debris
• Twelve white floss pads for fine particle removal
• Reusable sponge pads after rinsing, helping you save over time

Note: the package uses vacuum packing for the floss pads. The floss may look thinner, but this does not affect filtration performance. For best results, you can soak the sponge pads in water for 5–10 minutes to restore their original dimensions.

Key benefits and practical use

• Multistage filtration that captures visible debris while maintaining water flow, reducing cloudiness during routine maintenance
• White floss pads target fine particles, contributing to a clearer tank appearance
• Color-coded sponge pads simplify identifying each stage during cleaning sessions
• By providing an initial filtration barrier, these pads can help extend the life of other filter media
• Reusable sponge components support a cost-effective, lower-waste maintenance routine

Care, setup, and compatibility

• Rinse sponge pads after cleaning to reuse them and maintain performance
• To restore dimensions, soak sponges in clean water for 5–10 minutes before installing
• Ensure proper fit with SUNSUN HW-304B/404B/704B/3000 CF500 canisters to maximize effectiveness

In real-world use, you may notice crisper water and easier maintenance when the pads are refreshed on a schedule that matches tank load. Results vary with tank size, stocking levels, and overall filtration needs, but the combination of foam layers and floss is designed to offer flexible, practical filtration improvements without overhauling your existing setup.
