Seaweed Scraper Replacement Kit — 3-in-1 Cartridge: Metal, Plastic and Pad | Seachem

The Seachem Seaweed Scraper Replacement Kit is the complete replacement cartridge for the Seachem 3-in-1 scraper. This kit includes a new cartridge with an integrated plastic blade, a metal blade, and a soft pad—everything you need to restore your scraper to its original performance. Compatible with both Seachem scraper sizes (12" and 18").

Kit contents

• 1 replacement cartridge with integrated plastic blade — safe for glass and acrylic
• 1 metal blade — removes stubborn algae from glass only
• 1 soft pad — first choice for acrylic aquariums

Why replace the cartridge?

The blades and pads wear down over time and lose their cleaning effectiveness. A worn blade can also damage glass or acrylic. Seachem recommends replacing the cartridges regularly to maintain effective and safe cleaning.

Compatibility

The cartridge is compatible with the 12" (31 cm) and 18" (46 cm) Seachem 3-in-1 scrapers. It slides directly into the scraper head—simply remove the old cartridge and insert the new one. The blades are specific to the Seachem system and are not compatible with standard razor blades.

Why choose this kit from ReefSolution?

The replacement kit is the most economical way to restore all three blades in a single purchase. To replace only the metal blades, Seachem Algae Scraper Replacement Blades (3 pack) are available separately. For the soft pads only, Seachem Algae Scraper Replacement Scrub Pads (3 pack) are also available.
