Frequently Asked Questions

Q: Will the magnetic fish tank cleaner scratch my acrylic aquarium?

A: No. The scrubbing pads included with this magnetic aquarium cleaner are specifically designed to be safe on both glass and acrylic tank surfaces. For particularly tough algae, switch to the stainless steel blade — but take care to use the appropriate pad for acrylic to avoid any surface marks.

Q: How do I know which size magnetic cleaner to choose for my aquarium?

A: Select the Regular Version if your tank's glass wall is 8mm thick or less (typical for small and nano tanks). Choose the Extra-Strong Magnet Version if your glass is between 8mm and 12mm thick, which is common in medium to large aquariums. Matching the correct version to your glass thickness ensures optimal magnetic grip and effective cleaning.

Q: Does the magnetic aquarium algae scrubber require any batteries or power?

A: No batteries or power source are needed. This fish tank cleaner operates entirely through magnetic force — the outer magnet guides the inner scrubber along your tank wall without any electrical components, making it safe, simple, and always ready to use.

Q: What should I do if the inner scrubber falls to the bottom of the tank?

A: The inner piece is designed with a floating element, so if it does become detached, it will rise to the surface of the water where you can easily retrieve it without disturbing your fish or decorations.
