Replacement Algae Scraper Blades - Stainless Steel (10 Pack)

Keep your glass crystal clear without the elbow grease.

These replacement stainless steel blades fit most standard aquarium algae scrapers, so you can finally stop hunting around for the exact brand that matches your handle. Whether you're maintaining a lush planted tank or a thriving reef, sharp blades make all the difference. Dull ones smear algae around instead of cutting it cleanly off the glass.

Each pack comes with 10 fresh blades, giving you plenty of replacements to last through months of maintenance. Swap one in whenever you notice your scraper dragging or leaving streaks, and your glass will look freshly installed every time.

Why hobbyists love them

Sharp, precision-cut stainless steel slices through stubborn coralline, green spot algae, and diatom film without you having to press hard against the glass, which means less risk of scratches and a lot less frustration. They're safe for both freshwater and saltwater setups, and the universal sizing means they'll drop straight into Aquapro scrapers and most other popular brands on the market.

Two sizes to fit your scraper

• Small Blade: 4.2cm × 1.2cm (fits standard handheld scrapers)
• Large Blade: 6.2cm × 1.6cm (fits long-reach and magnetic scrapers)

Not sure which one fits your scraper? Measure the slot on your existing blade holder. The dimensions above match the two most common industry standards.
