Aquarium Magnetic Glass Cleaners

Shop magnetic aquarium cleaners for removing light algae from the inside surface while keeping your hands outside the tank. Current listings include floating magnetic cleaners in sizes suited to different panel thicknesses, subject to stock.

Choose for the aquarium material and actual panel thickness. A magnet that is too weak may separate, while trapped sand or grit can scratch glass and especially acrylic.

Choosing a Magnetic Aquarium Cleaner

Check the individual product’s stated aquarium material, maximum panel thickness and dimensions before purchase. Do not assume that every magnetic cleaner is safe for acrylic.

  • Measure the aquarium panel thickness.
  • Confirm glass or acrylic compatibility.
  • Choose a size that can reach the areas you need to clean.
  • Inspect both pads for grit before every use.

Floating Magnetic Cleaners

A floating internal pad is easier to retrieve when the magnets separate, but buoyancy does not make the tool suitable for every tank or surface.

Avoiding Scratches

Keep the cleaner above the substrate and never drag sand or gravel between the pad and aquarium wall. Rinse the pads and inspect them carefully before reuse.

Corners and Silicone Seams

Move slowly near corners and silicone joins. A magnetic cleaner is intended for flat viewing panels and should not be forced across seals, curved areas or damaged surfaces.

Using a Magnetic Cleaner Safely

Clean with steady overlapping passes and keep the wet pad fully submerged. Separate the magnets gently rather than allowing them to snap together outside the aquarium.

For stubborn deposits, use an appropriate aquarium cleaning tool that is confirmed safe for the tank material.

Frequently Asked Questions

Can magnetic aquarium cleaners scratch glass?

Yes. Sand, grit or damaged pads trapped against the panel can cause scratches, so inspect and rinse the cleaner before use.

Can I use a glass magnetic cleaner on acrylic?

Only if the manufacturer specifically states that it is suitable for acrylic. Acrylic scratches more easily.

What size magnetic cleaner do I need?

Choose a model rated for the aquarium’s actual panel thickness and with dimensions suitable for the area being cleaned.

Why does my magnetic cleaner keep separating?

The panel may be thicker than the cleaner’s rating, the pads may be obstructed, or the magnets may not be aligned correctly.

Should a magnetic cleaner be used near the substrate?

Use extra care near substrate because trapped sand or gravel can scratch the aquarium panel.
