Stainless Steel Algae Scraper for Aquarium Glass — Fixed & Adjustable

Blade-clean glass in one pass — tough on stubborn algae, gentle on your scape.

Keep your aquarium glass crystal clear with this stainless steel algae scraper — a professional-grade cleaning tool for aquascapers who want to remove hard, stuck-on algae without draining the tank or reaching in shoulder-deep. The sharp blade lifts green spot algae, green dust algae, and biofilm that magnet cleaners and sponges leave behind, so your display panel stays showroom-clear between water changes.

Why Aquascapers Choose This Scraper

• 🔩 Solid stainless steel handle — rust-resistant, sturdy, and no plastic flex mid-scrape
• 🪒 Sharp blade head — removes stubborn green spot algae (GSA) that magnet cleaners can't touch
• 🔧 Detachable rod sections — adjust the length to your tank and break it down flat for storage
• 🏖️ Blade cover doubles as a flat sand shovel — level and shape substrate with the same tool
• 📏 Four sizes (30cm–90cm) — from nano cubes to deep display tanks

⚠️ Glass tanks only. Metal blades permanently scratch acrylic — acrylic owners should use a plastic-blade scraper instead. On glass, keep the blade at a shallow angle, avoid dragging substrate grit up the panel, and stay clear of silicone seams.

💡 Pro tip: Scrape the glass 30–60 minutes before your water change, then siphon out the loosened algae so it doesn't resettle on your plants and hardscape.

Your Top 5 Questions — Answered

1. Will the metal blade scratch my aquarium glass?

= No — used correctly, a razor blade is one of the safest ways to clean aquarium glass. Scratches almost never come from the blade itself; they come from sand or grit trapped under the edge. Keep the blade at a shallow angle, wipe the edge between passes, and don't scrape below the substrate line.

2. Can I use it on an acrylic tank?

= No — this scraper is for glass tanks only. Metal blades gouge acrylic instantly and permanently. If you run an acrylic tank, use a plastic blade or acrylic-safe scraper instead.

3. Which size should I pick for my tank?

= Match the handle length to your tank's depth:

• 30cm (~12") — nano and desktop tanks up to ~10 gallons
• 40cm (~16") — 10–29-gallon standard tanks
• 65cm (~26") — 40–75-gallon tanks
• 90cm (~35") — deep or tall display tanks (75+ gallons), or anytime you'd rather keep your sleeves dry

4. Does it actually remove green spot algae (GSA)?

= Yes — hard, crusty algae like GSA is exactly what a blade scraper is for. GSA bonds tightly to glass and shrugs off magnet cleaners and sponges, but the blade lifts it in a single pass. In planted tanks, persistent GSA is often a low-phosphate signal — so scrape the glass, then check your nutrient dosing to keep it from coming back.

5. Will the blade rust inside the aquarium?

= Not during use — but store it dry. The stainless steel handle resists corrosion, and a short cleaning session won't harm the blade. After each use, rinse the head in freshwater (especially after saltwater use) and dry it fully before capping the cover. Swap in a fresh blade whenever the edge dulls — spares are included.
