Mag-Float vs Flipper
Two floating magnetic cleaners for the same job — keeping the front glass clear — but built for different algae. The Mag-Float 125 is the simple felt magnet for everyday film; the Flipper Standard flips to a steel blade for hard, crusty spots. Here's which one your tank needs, and why many keepers own both.
The quick verdict
These are complements more than rivals. For the weekly soft green film — the routine chore — the Mag-Float 125 is faster, cheaper and more foolproof, so it's the daily driver. When your tank grows hard, crusty spot algae or coralline that a felt pad just slides over, the Flipper Standard flips to a stainless blade and shears it off. Buy the Mag-Float first; add the Flipper if you get the stubborn stuff.
| Mag-Float 125 | Flipper Standard | |
|---|---|---|
| Soft green film | Fast, foolproof | Handles it (scrub side) |
| Hard spot algae | No — pad slides over | Yes — flips to steel blade |
| Glass thickness | Up to ~10 mm | Up to 12 mm |
| Acrylic-safe option | No blade | Yes (plastic blade) |
| Price | Cheaper (≈ $24) | Pricier (≈ $35) |
| Size / nano use | Slimmer, easier in corners | Bulkier |
| Best for | Everyday film | Hard, crusty spots |
Felt pad vs flip-to-blade
The core difference is what each can shift. The Mag-Float is a one-piece felt magnet: drag the outside half and the inner pad wipes soft film clean in seconds, hands dry. It's brilliant for the routine job but the felt will not touch hard, crusty spot algae. The Flipper puts two tools in one body — a felt scrubber on one face and a stainless blade on the other — and a twist of the handle switches between them, so you scrub the film and then shear off the stubborn spots without wet sleeves. It also handles thicker glass (12 mm vs ~10 mm) and ships with a plastic blade for acrylic.
The rule that matters: grit
Every scratch story with a magnet cleaner comes down to a grain of sand caught in the pad or blade — and that risk is higher with the Flipper's steel edge. For both, keep the cleaner away from the substrate line, rinse before use, and lift it cleanly off the glass rather than dragging it down. And remember: wiping glass is cosmetic. The real algae control is nutrient control — a weekly 25–30% water change, a 6–8 hour photoperiod and not overfeeding.
Our pick
Start with the Mag-Float 125 — it makes the weekly wipe a five-second job you'll actually do, and for most tanks that's all you need. Add the Flipper Standard if your glass grows hard spot algae or you keep a marine tank with coralline.

Frequently asked questions
Do I need a Flipper if I already have a Mag-Float?
Only if you get hard algae. A felt magnet like the Mag-Float handles the weekly soft green film perfectly and is faster and cheaper for that job. Where it slides helplessly over crusty spot algae or coralline, the Flipper flips to a stainless blade and shears it off. If your glass only ever grows soft film, the plain magnet is enough; the Flipper earns its price on tanks that get stubborn spots.
Which is safer for my glass?
Both are safe used carefully, and both share the same rule: keep the pad or blade away from the substrate line so it cannot pick up a grain of grit, which is what actually scratches glass. The Flipper's steel blade demands more care and you must switch to its plastic blade on acrylic. The Mag-Float is more foolproof for everyday use.
Which fits a nano tank better?
The Mag-Float 125 is slimmer and easier in tight corners, and Mag-Float makes an even smaller 30 for nanos. The Flipper is bulkier and fiddlier in the corners of a small tank. For a nano, the Mag-Float is the more comfortable everyday cleaner.
