Before You Buy
Key Buying Factors
01
Glass thickness rating
Match the magnet strength to your glass. A magnet too weak for thick glass loses grip and stalls, so check the maximum thickness rating before buying.
02
Scratch safety
Grit trapped under the pad is what scratches glass. Lift the cleaner out to rinse if it picks up sand, and use an acrylic-safe pad on acrylic tanks.
03
Blade versus pad
A blade tackles stubborn coralline or hard algae, while a pad handles daily green film. Two-in-one designs cover both jobs.
04
Floating design
A cleaner that floats if the two halves separate is far easier to retrieve than one that sinks into the substrate.
05
Glass or acrylic
Use only acrylic-safe cleaners on acrylic tanks, as a glass blade will scratch acrylic permanently. Check the product suits your tank material.
06
Reach and grip
A comfortable outer handle and a slim inner block let you reach corners and clean right down near the substrate without disturbing the scape.
Frequently asked questions
Will a magnetic algae cleaner scratch my glass?
It can if it traps sand or grit under the pad. Keep the cleaner away from the substrate, lift it out to rinse if it picks up grit, and use an acrylic-safe version on acrylic tanks to avoid scratches.
How strong a magnet do I need?
Match the magnet to your glass thickness. Check the product's maximum thickness rating, since a magnet too weak for thick glass will keep losing grip and stalling as you push it around.
How often should I clean aquarium glass?
A quick wipe with a magnet cleaner every few days keeps the view clear and stops algae building into a stubborn layer. Regular light cleaning is far easier than tackling a thick, established film.
