Fluval Replacement Razor (3) Magnet Small
Genuine Fluval blades for the Razor+ 2-in-1 Algae Magnet, Small. This is a pack of three replacement scraper blades for aquariums with up to 6 mm glass thickness – the small-format Razor+ magnetic cleaner, not the medium unit.
The Razor+ handle combines a soft non-abrasive scrubber pad with a removable, replaceable blade for stubborn coralline and green-spot algae. The blade dulls with use long before the magnet itself wears out, so buying the blade pack on its own keeps the tool working without replacing the whole cleaner.
Key features
- Genuine Fluval part #11085 – the correct blade for the Small Razor+ magnet, not a generic fit.
- 316 stainless steel – corrosion-resistant in both freshwater and marine systems.
- Pack of three – spare blades ready for when the fitted one dulls.
- Tool-free swap – the blade clips out of the handle without disassembling the magnet.
- Rated to 6 mm glass – matched to the Small Razor+ housing's magnet strength.
Will it fit my magnet cleaner?
These blades fit the Fluval Razor+ 2-in-1 Algae Magnet, Small only – the version rated for aquarium glass up to 6 mm thick. Fluval also sells a Medium Razor+ rated to 10 mm glass; that unit takes a different, larger blade (Fluval #11086) and is not compatible with this pack. Check the glass thickness of your tank and the size marked on your existing magnet handle before ordering.

Common questions
How do I know if I have the Small or Medium Razor+?
The Small handle is rated to 6 mm glass and is the shorter of the two housings; the Medium is rated to 10 mm. The rating is printed on the underside of the handle.
Will these blades scratch acrylic?
Yes – stainless steel blades are not acrylic-safe. Use Fluval's soft-pad-only mode, or a dedicated acrylic-safe cleaner, on acrylic tanks.
How often does the blade need replacing?
It depends on algae load and how often the magnet is used, but a dulled blade stops cutting coralline cleanly and starts skipping – that's the sign to swap it.
Can I use this blade in saltwater?
Yes. 316 stainless steel is corrosion-resistant in both freshwater and marine water.
