The Mag-Float scraper blades are replacement/upgrade blades used with the **Mag-Float magnetic glass cleaners. They attach to the floating magnet side and let you switch from a soft algae pad to a hard scraper blade for tougher buildup.

What they’re used for

The blade snaps onto the Mag-Float inner magnet
You move the outer magnet outside the tank → the blade scrapes inside
Floating design means the inner piece rises if it detaches

Blade types you’ll usually see
Plastic blade → safer for acrylic tanks (less scratching risk)
Stainless steel blade → stronger, best for glass only (marine reef tanks)
Some kits include replaceable edge inserts
Important warnings
Only use stainless blades on glass tanks, not acrylic
Don’t trap sand between blade and glass (can scratch)
Rinse after saltwater use to prevent corrosion buildup
