Buying Guide

Match cleaner to tank material

Choose acrylic-safe scrapers for plastic tanks and harder blades or magnets for glass to avoid scratching or damage

Magnet strength and thickness

Stronger magnets and thicker casings work better on deep tanks and through thicker glass, while slim magnets fit narrow frames

Scraper head and blade types

Look for replaceable blades or dual-sided heads (scrubber + blade) so you can switch between scraping and gentle cleaning

Ease of use and grip

Ergonomic handles and tethered safety cords reduce hand fatigue and prevent outer magnets from dropping into water during use

Live cleaners vs tools

Amano shrimp and other live cleaners can supplement manual tools in nano setups, but they’re slower and require compatible tank conditions

Electric and multi-function kits

Electric scrapers and kits add speed and convenience but weigh more and need waterproofing and battery or charging considerations
