Magnetic vs Handheld Algae Scraper
Magnetic algae cleaner vs a long handled scraper compared: reach, scratching risk, sand grit, acrylic tanks and which to use.
The short version
A magnet cleans without putting your arm in the tank, which is genuinely convenient on a weekly basis. A long handled blade reaches corners and shifts hard coralline or stubborn spot algae a magnet slides over. Both can scratch glass if grit gets trapped. Use the magnet for routine cleaning; keep a blade scraper for the stubborn patches and the corners.

Choose the Aqueon Magnetic Algae Scraper if…
You clean the front glass weekly and would rather not roll up a sleeve. Check the magnet faces for trapped sand before every use, because a single grain dragged across glass leaves a permanent scratch.

Choose the 25.6 in Stainless Steel Algae Scraper if…
You have spot algae the magnet skates over, or you need to reach into corners and behind decor. Never use a metal blade on an acrylic tank: acrylic scratches far more easily than glass and a blade will ruin it.

Frequently Asked Questions
How do I stop scratching the glass?
Inspect and rinse the cleaning surface before every use, and keep the magnet clear of the substrate line where it picks up grit. Most tank scratches come from a single trapped grain rather than the tool itself.
What causes persistent algae?
Excess light and excess nutrients, in some combination. Shortening the photoperiod and increasing water changes addresses the cause; scraping only manages the symptom.
Is algae actually harmful?
Usually not to the fish, and it is unsightly and a signal about the tank's balance. Sudden heavy algae growth often follows overfeeding or a light left on too long.
