Filter Pad Set for SunSun HW-303B, 403B (3x White, 1x Blue)

Product details

Filter Pad Set for SunSun HW-303B, 403B (3x White, 1x Blue) is a replacement canister filter pad set for compatible SUNSUN canister models. It replaces worn filter media inside the filter to help maintain both mechanical and biological filtration. In practical use, these sponge pads capture a range of debris sizes while also providing surface area for beneficial bacteria, helping keep water looking clear and reducing fine suspended particles.

Features:

• Includes multiple sponge grades (coarse, medium, and fine) to capture debris from larger to smaller particles
• Supports mechanical filtration by trapping visible particles without unduly restricting water flow
• Supports biological filtration by providing additional media surface for beneficial bacteria
• Designed for routine media replacement and is reusable after rinsing, depending on your maintenance schedule
• Helps reduce fine particulates that can cloud aquarium water
• Color-coded pads (3x White, 1x Blue) make it easier to sort and reinstall the set correctly
