Borlech 8-Layer Aquarium Filter Pad

The Borlech 8-Layer Aquarium Filter Pad stacks several materials into one sheet: a three-dimensional honeycomb mesh, fiber cotton and a fine non-adhesive mesh. Each layer catches a smaller size of particle, so one pad covers both coarse and fine mechanical filtration.

Size

The pad is 15.75 x 11.81 x 0.6 inches and comes as a single sheet. Cut it to fit your filter tray, HOB media slot or sump.

What it removes

Fish waste, uneaten food and small floating particles that make water look dull. Borlech pitches it for fast polishing, the kind of job you do after a gravel clean or when a tank goes hazy.

Flow

Even with the layers, water passes through freely, so it won’t starve your filter of flow when it’s clean. As it fills with debris, flow drops. That’s your cue to rinse it.

Setup

• Measure the space and cut the pad to size.
• Place it after any coarse sponge, before bio media.
• Check it after a few days the first time to learn how fast it loads up.

Cleaning and reuse

Rinse the pad in old tank water and squeeze gently. The mixed materials hold up to repeated cleaning. Replace it once it no longer springs back or stays discolored.

One tip: mark which face is the upstream side when you cut it. Keeping the coarser layer facing incoming water lets each layer do its intended job, and the pad lasts longer between rinses. If you flip it by mistake, the fine layer clogs first and flow drops quickly.

Alternatives

For a cheaper single-layer polish, the MAQIHAN floss pad works. For a fine-pore pad that stays in place, see the Aquatic Experts polishing pad.
