Tunze Care Magnet Nano 0220.010

The Tunze Care Magnet Nano 0220.010 is a compact, high‑precision magnetic algae scraper designed for glass aquariums 1/4" to 3/8" thick (6–10 mm). Its engineering focuses on scratch prevention, tight‑space maneuverability, and efficient algae removal, making it ideal for nano and desktop reef tanks like the ones you stock at Seahorse Aquarium & Supply. 🧼 Core Takeaway A slim, safe‑for‑reef magnetic algae cleaner with wear‑resistant plastic blades, engineered to avoid sand scratches and reach tight corners—perfect for nano tanks with 6–10 mm glass. 🧩 Key Features & Design Glass thickness: 6–10 mm (1/4"–3/8") compatibility Slim profile: 45 mm wide × 78 mm long—easy to maneuver around rockwork and corals Inner magnet spacing: Sits >3 mm away from the glass, reducing sand entrapment and scratch risk Plastic blades: Wear‑resistant, high‑performance polymer; lasts months to ~1 year depending on use Rounded blade corners: Protect silicone seams and allow smooth transitions around edges and curved glass Low flow resistance: Strong magnetic coupling prevents accidental separation during cleaning Includes: 1 × 45 mm replacement plastic blade 8 colored end caps (blue, green, white, black) 🧪 Performance & Cleaning Behavior Removes algae more effectively than flat magnets—nearly as good as a metal blade, but safer for glass Two blade lengths create varied pressure: Narrow blade = stubborn algae removal Wide blade = fast, large‑area cleaning Does not smear algae: Rolls it up instead of distributing green dust—fish often eat the rolled algae Safe for reef tanks: Slim design avoids disturbing corals and plants during cleaning 🛡️ Safety Notes Glass only recommended. Acrylic use is not recommended by Tunze; if attempted, only short blades should be used and felt kept perfectly clean to avoid scratches. Check for sand/grit before each use—scratches can occur if contaminants are trapped. Optional stainless steel blade (for tough calcareous algae) should only be used on glass, never acrylic. 🌊 Use Cases Perfect for: Nano reefs and desktops (like Red Sea 20–30g class tanks) Tanks with tight rockwork or curved glass Daily/weekly algae maintenance Hobbyists wanting a low‑profile scraper that can stay in the tank without being visually intrusive
